+# Polkadot Omni Node
+
+This is a white labeled implementation based on [`polkadot-omni-node-lib`](https://crates.io/crates/polkadot-omni-node-lib).
+It can be used to start a parachain node from a provided chain spec file. It is only compatible with runtimes that use block
+number `u32` and `Aura` consensus.
+
+## Installation
+
+Download & expose it via `PATH`:
+
+```bash
+# Download and set it on PATH.
+wget https://github.com/paritytech/polkadot-sdk/releases/download/<stable_release_tag>/polkadot-omni-node
+chmod +x polkadot-omni-node
+export PATH="$PATH:`pwd`"
+```
+
+Compile & install via `cargo`:
+
+```bash
+# Assuming ~/.cargo/bin is on the PATH
+cargo install polkadot-omni-node
+```
+
+## Usage
+
+A basic example for an Omni Node run starts from a runtime which implements the [`sp_genesis_builder::GenesisBuilder`](https://docs.rs/sp-genesis-builder/latest/sp_genesis_builder/trait.GenesisBuilder.html).
+The interface mandates the runtime to expose a [`named-preset`](https://docs.rs/staging-chain-spec-builder/latest/staging_chain_spec_builder/#generate-chain-spec-using-runtime-provided-genesis-config-preset).
+
+### 1. Install chain-spec-builder
+
+**Note**: `chain-spec-builder` binary is published on [`crates.io`](https://crates.io) under
+[`staging-chain-spec-builder`](https://crates.io/crates/staging-chain-spec-builder) due to a name conflict.
+Install it with `cargo` like bellow :
+
+```bash
+cargo install staging-chain-spec-builder
+```
+
+### 2. Generate a chain spec
+
+Omni Node expects for the chain spec to contain parachains related fields like `relay_chain` and `para_id`.
+These fields can be introduced by running [`staging-chain-spec-builder`](https://crates.io/crates/staging-chain-spec-builder)
+with additional flags:
+
+```bash
+chain-spec-builder create --relay-chain <relay_chain_id> --para-id <id> -r <runtime.wasm> named-preset <preset_name>
+```
+
+### 3. Run Omni Node
+
+And now with the generated chain spec we can start Omni Node like so:
+
+```bash
+polkadot-omni-node --chain <chain_spec.json>
+```
+
+## Useful links

+# Polkadot Omni Node Library
+
+Helper library that can be used to run a parachain node.
+
+## Overview
+
+This library can be used to run a parachain node while also customizing the chain specs
+that are supported by default by the `--chain-spec` argument of the node's `CLI`
+and the parameters of the runtime that is associated with each of these chain specs.
+
+## API
+
+The library exposes the possibility to provide a [`RunConfig`]. Through this structure
+2 optional configurations can be provided:
+- a chain spec loader (an implementation of [`chain_spec::LoadSpec`]): this can be used for
+  providing the chain specs that are supported by default by the `--chain-spec` argument of the
+  node's `CLI` and the actual chain config associated with each one.
+- a runtime resolver (an implementation of [`runtime::RuntimeResolver`]): this can be used for
+  providing the parameters of the runtime that is associated with each of the chain specs
+
+Apart from this, a [`CliConfig`] can also be provided, that can be used to customize some
+user-facing binary author, support url, etc.
+
+## Examples
+
+For an example, see the [`polkadot-parachain-bin`](https://crates.io/crates/polkadot-parachain-bin) crate.

-//! # XCM Version 2
-//!
-//! WARNING: DEPRECATED, please use version 3 or 4.
-//!
-//! Version 2 of the Cross-Consensus Message format data structures. The comprehensive list of
-//! changes can be found in
-//! [this PR description](https://github.com/paritytech/polkadot/pull/3629#issue-968428279).
-//!
-//! ## Changes to be aware of
-//! The biggest change here is the restructuring of XCM messages: instead of having `Order` and
-//! `Xcm` types, the `Xcm` type now simply wraps a `Vec` containing `Instruction`s. However, most
-//! changes should still be automatically convertible via the `try_from` and `from` conversion
-//! functions.
-//!
-//! ### Junction
-//! - No special attention necessary
-//!
-//! ### `MultiLocation`
-//! - No special attention necessary
-//!
-//! ### `MultiAsset`
-//! - No special attention necessary
-//!
-//! ### XCM and Order
-//! - `Xcm` and `Order` variants are now combined under a single `Instruction` enum.
-//! - `Order` is now obsolete and replaced entirely by `Instruction`.
-//! - `Xcm` is now a simple wrapper around a `Vec<Instruction>`.
-//! - During conversion from `Order` to `Instruction`, we do not handle `BuyExecution`s that have
-//!   nested XCMs, i.e. if the `instructions` field in the `BuyExecution` enum struct variant is not
-//!   empty, then the conversion will fail. To address this, rewrite the XCM using `Instruction`s in
-//!   chronological order.
-//! - During conversion from `Xcm` to `Instruction`, we do not handle `RelayedFrom` messages at all.
-//!
-//! ### XCM Pallet
-//! - The `Weigher` configuration item must have sensible weights defined for `BuyExecution` and
-//!   `DepositAsset` instructions. Failing that, dispatch calls to `teleport_assets` and
-//!   `reserve_transfer_assets` will fail with `UnweighableMessage`.

-//! This encompasses four types for representing assets:
-//! - `MultiAsset`: A description of a single asset, either an instance of a non-fungible or some
-//!   amount of a fungible.
-//! - `MultiAssets`: A collection of `MultiAsset`s. These are stored in a `Vec` and sorted with

-/// A relative path between state-bearing consensus systems.
-///
-/// A location in a consensus system is defined as an *isolatable state machine* held within global
-/// consensus. The location in question need not have a sophisticated consensus algorithm of its
-/// own; a single account within Ethereum, for example, could be considered a location.
-///
-/// A very-much non-exhaustive list of types of location include:
-/// - A (normal, layer-1) block chain, e.g. the Bitcoin mainnet or a parachain.
-/// - A layer-0 super-chain, e.g. the Polkadot Relay chain.
-/// - A layer-2 smart contract, e.g. an ERC-20 on Ethereum.
-/// - A logical functional component of a chain, e.g. a single instance of a pallet on a Frame-based
-///   Substrate chain.
-/// - An account.
-///
-/// A `MultiLocation` is a *relative identifier*, meaning that it can only be used to define the
-/// relative path between two locations, and cannot generally be used to refer to a location
-/// universally. It is comprised of an integer number of parents specifying the number of times to
-/// "escape" upwards into the containing consensus system and then a number of *junctions*, each
-/// diving down and specifying some interior portion of state (which may be considered a
-/// "sub-consensus" system).
-///
-/// This specific `MultiLocation` implementation uses a `Junctions` datatype which is a Rust `enum`
-/// in order to make pattern matching easier. There are occasions where it is important to ensure
-/// that a value is strictly an interior location, in those cases, `Junctions` may be used.
-///
-/// The `MultiLocation` value of `Null` simply refers to the interpreting consensus system.

+/// A location in a consensus system is defined as an *isolatable state machine* held within global

+///
+/// A very-much non-exhaustive list of types of location include:
+/// - A (normal, layer-1) block chain, e.g. the Bitcoin mainnet or a parachain.
+/// - A layer-0 super-chain, e.g. the Polkadot Relay chain.
+/// - A layer-2 smart contract, e.g. an ERC-20 on Ethereum.
+/// - A logical functional component of a chain, e.g. a single instance of a pallet on a Frame-based
+///   Substrate chain.
+/// - An account.

+/// diving down and specifying some interior portion of state (which may be considered a
+/// "sub-consensus" system).

+///
+/// The `Location` value of `Null` simply refers to the interpreting consensus system.

+title: Update Treasury to Support Block Number Provider
+
+doc:
+  - audience: Runtime Dev
+    description: |
+      The goal of this PR is to have the treasury pallet work on a parachain which does not produce blocks on a regular schedule, thus can use the relay chain as a block provider. Because blocks are not produced regularly, we cannot make the assumption that block number increases monotonically, and thus have new logic to handle multiple spend periods passing between blocks. To migrate existing treasury implementations, simply add `type BlockNumberProvider = System` to have the same behavior as before.

+title: "`impl_runtime_apis!`: replace the use of `Self` with `Runtime`"
+
+doc:
+  - audience: Runtime Dev
+    description: |
+        Currently, if there is a type alias similar to `type HeaderFor<T>` in the scope, it makes sense to expect that
+        `HeaderFor<Runtime>` and `HeaderFor<Self>` are equivalent. However, this is not the case. It currently leads to 
+        a compilation error that `Self is not in scope`, which is confusing. This PR introduces a visitor, similar to 
+        `CheckTraitDecl` in `decl_runtime_apis!`, `ReplaceSelfImpl`. It identifies usage of `Self` as a type argument in
+        `impl_runtime_apis!` and replaces `Self` with an explicit `Runtime` type.
+
+        For example, the following example code will be transformed before expansion:
+        ```rust
+        impl apis::Core<Block> for Runtime {
+            fn initialize_block(header: &HeaderFor<Self>) -> ExtrinsicInclusionMode {
+                let _: HeaderFor<Self> = header.clone();
+                RuntimeExecutive::initialize_block(header)
+            }
+        }
+        ``` 
+        Instead, it will be passed to macro as:
+        ```rust
+        impl apis::Core<Block> for Runtime {
+            fn initialize_block(header: &HeaderFor<Runtime>) -> ExtrinsicInclusionMode {
+                let _: HeaderFor<Runtime> = header.clone();
+                RuntimeExecutive::initialize_block(header)
+            }
+        }
+        ```

+title: XCMv5
+
+doc:
+  - audience: [Runtime User, Runtime Dev]
+    description: |
+      Added XCMv5.
+
+      This PR brings a new XCM version.
+      It's an amalgamation of multiple individual PRs:
+      - https://github.com/paritytech/polkadot-sdk/pull/6228
+      - https://github.com/paritytech/polkadot-sdk/pull/6148
+      - https://github.com/paritytech/polkadot-sdk/pull/5971
+      - https://github.com/paritytech/polkadot-sdk/pull/5876
+      - https://github.com/paritytech/polkadot-sdk/pull/5420
+      - https://github.com/paritytech/polkadot-sdk/pull/5585
+
+      XCMv5 reduces the potential for bugs by:
+      - Removing the need to specify weight in Transact.
+      - Handling fees in a better way with `PayFees` instead of `BuyExecution`.
+      - Improves asset claiming with `SetAssetClaimer`.
+
+      It also allows some new use-cases like:
+      - Sending both teleported and reserve asset transferred assets in the same cross-chain
+      transfer.
+      - Preserving the origin when doing cross-chain transfers. Allowing the use of Transact
+      in the same message as a cross-chain transfer.
+
+      In version 5, it's expected to change usage of `BuyExecution` to `PayFees`.
+      While `BuyExecution` returns all leftover assets to holding, `PayFees` doesn't.
+      The only way to get funds back from those sent to `PayFees` is by using `RefundSurplus`.
+      Because of this, it's meant to be used alongside the new DryRunApi and XcmPaymentApi.
+      You first dry-run the XCM, get the fees needed, and put them in `PayFees`.

+title: XCMv5 - Better fee mechanism
+
+doc:
+  - audience:
+    - Runtime User
+    - Runtime Dev
+    description: |
+      In XCMv5, there's a new instruction, `PayFees`, which is meant to be a replacement for `BuyExecution`.
+      This instruction takes only one parameter, the `asset` that you are willing to use for fee payment.
+      There's no parameter for limiting the weight, the amount of the `asset` you put in is the limit of
+      how much you're willing to pay.
+      This instruction works much better with delivery fees.
+      `BuyExecution` will still be around to ensure backwards-compatibility, however, the benefits of the new
+      instruction are a good incentive to switch.
+      The proposed workflow is to estimate fees using the `XcmPaymentApi` and `DryRunApi`, then to put those
+      values in `PayFees` and watch your message go knowing you covered all the necessary fees.
+      You can add a little bit more just in case if you want.
+      `RefundSurplus` now gets back all of the assets that were destined for fee payment so you can deposit
+      them somewhere.
+      BEWARE, make sure you're not sending any other message after you call `RefundSurplus`, if not, it will
+      error.

+      Changing `sale_start`, `interlude_length` and `leading_length` in `pallet_broker` to use relay chain block numbers instead of parachain block numbers.
+      Relay chain block numbers are almost deterministic and more future proof.

+title: Make syncing service an argument of `build_network`
+
+doc:
+  - audience: Node Dev
+    description: |
+      `build_network` is accompanied with lower-level `build_network_advanced` with simpler API that does not create
+      syncing engine internally, but instead takes a handle to syncing service as an argument. In most cases typical
+      syncing engine with polkadot syncing strategy and default block downloader can be created with newly introduced
+      `sc_service::build_default_syncing_engine()` function, but lower-level `build_default_block_downloader` also
+      exists for those needing more customization.
+
+      These changes allow developers higher than ever control over syncing implementation, but `build_network` is still
+      available for easier high-level usage.

+title: (XCMv5) implement RFC#100, add new InitiateTransfer instruction
+
+doc:
+  - audience: Runtime Dev
+    description: |
+      There's a new XCM instruction in v5: InitiateTransfer.
+      It's meant as a general instruction that will do everything (and more) currently
+      done by InitiateTeleport, InitiateReserveWithdraw and DepositReserveAsset.
+      Its main feature is the ability to do cross-chains transfers mixing teleported and
+      reserve transferred assets.
+      ```rust
+      /// Specify which type of asset transfer is required for a particular `(asset, dest)` combination.
+      pub enum AssetTransferFilter {
+      	/// teleport assets matching `AssetFilter` to `dest`
+      	Teleport(AssetFilter),
+      	/// reserve-transfer assets matching `AssetFilter` to `dest`, using the local chain as reserve
+      	ReserveDeposit(AssetFilter),
+      	/// reserve-transfer assets matching `AssetFilter` to `dest`, using `dest` as reserve
+      	ReserveWithdraw(AssetFilter),
+      }
+      /// Cross-chain transfer matching `assets` in the holding register as follows:
+      ///
+      /// Assets in the holding register are matched using the given list of `AssetTransferFilter`s,
+      /// they are then transferred based on their specified transfer type:
+      ///
+      /// - teleport: burn local assets and append a `ReceiveTeleportedAsset` XCM instruction to
+      ///   the XCM program to be sent onward to the `dest` location,
+      ///
+      /// - reserve deposit: place assets under the ownership of `dest` within this consensus system
+      ///   (i.e. its sovereign account), and append a `ReserveAssetDeposited` XCM instruction
+      ///   to the XCM program to be sent onward to the `dest` location,
+      ///
+      /// - reserve withdraw: burn local assets and append a `WithdrawAsset` XCM instruction
+      ///   to the XCM program to be sent onward to the `dest` location,
+      ///
+      /// The onward XCM is then appended a `ClearOrigin` to allow safe execution of any following
+      /// custom XCM instructions provided in `remote_xcm`.
+      ///
+      /// The onward XCM also potentially contains a `BuyExecution` instruction based on the presence
+      /// of the `remote_fees` parameter (see below).
+      ///
+      /// If a transfer requires going through multiple hops, an XCM program can compose this instruction
+      /// to be used at every chain along the path, describing that specific leg of the transfer.
+      ///
+      /// Parameters:
+      /// - `dest`: The location of the transfer next hop.
+      /// - `remote_fees`: If set to `Some(asset_xfer_filter)`, the single asset matching
+      ///   `asset_xfer_filter` in the holding register will be transferred first in the remote XCM
+      ///   program, followed by a `BuyExecution(fee)`, then rest of transfers follow.
+      ///   This guarantees `remote_xcm` will successfully pass a `AllowTopLevelPaidExecutionFrom` barrier.
+      /// - `remote_xcm`: Custom instructions that will be executed on the `dest` chain. Note that
+      ///   these instructions will be executed after a `ClearOrigin` so their origin will be `None`.
+      ///
+      /// Safety: No concerns.
+      ///
+      /// Kind: *Command*.
+      ///
+      InitiateTransfer {
+      	destination: Location,
+      	remote_fees: Option<AssetTransferFilter>,
+      	assets: Vec<AssetTransferFilter>,

+title: XCMv5 InitiateTransfer can preserve original origin across chains.
+
+doc:
+  - audience: Runtime User
+    description: |
+      The new InitiateTransfer instruction can preserve the original origin across chains by
+      setting `preserve_origin: true` in the instruction itself.
+      When it's set to true, it will append after the inner XCM, an `AliasOrigin` instruction
+      instead of the usual `ClearOrigin`.
+      This instruction will try to alias to the original origin, thus preserving it.
+      This only works if the chain receiving the transfer supports the aliasing operation.
+      If not, `preserve_origin: false` works as before and will never fail because of this.

+      - AliasChildLocation
+      - AliasOriginRootUsingFilter with AssetHub and Everything
+      An example of the first one can be seen in `asset-hub-westend` and of the second one in

+title: "[Deprecation] deprecate treasury `spend_local` call and related items"
+
+doc:
+  - audience: Runtime Dev
+    description: |
+      Deprecates `spend_local` from the treasury pallet and items associated with it.
+
+      ### Migration
+
+      #### For users who were using only `spend_local` before
+
+      To replace `spend_local` functionality configure `Paymaster` pallet configuration to be `PayFromAccount` and configure `AssetKind` to be `()` and use `spend` call instead.
+      This way `spend` call will function as deprecated `spend_local`.
+
+      Example:
+      ```
+      impl pallet_treasury::Config for Runtime {
+        ..
+        type AssetKind = ();
+        type Paymaster = PayFromAccount<Self::Currency, TreasuryAccount>;
+        // convert balance 1:1 ratio with native currency
+        type BalanceConverter = UnityAssetBalanceConversion;
+        ..
+      }
+      ```
+
+      #### For users who were already using `spend` with all other assets, except the native asset
+
+      Use `NativeOrWithId` type for `AssetKind` and have a `UnionOf` for native and non-native assets, then use that with `PayAssetFromAccount`.
+
+      Example from `kitchensink-runtime`:
+      ```
+      // Union of native currency and assets
+      pub type NativeAndAssets =
+        UnionOf<Balances, Assets, NativeFromLeft, NativeOrWithId<u32>, AccountId>;
+
+      impl pallet_treasury::Config for Runtime {
+        ..
+        type AssetKind = NativeOrWithId<u32>;
+        type Paymaster = PayAssetFromAccount<NativeAndAssets, TreasuryAccount>;
+        type BalanceConverter = AssetRate;
+        ..
+      }
+
+      // AssetRate pallet configuration
+      impl pallet_asset_rate::Config for Runtime {
+        ..
+        type Currency = Balances;
+        type AssetKind = NativeOrWithId<u32>;

+title: '[pallet-revive] rework balance transfers'
+doc:
+- audience: Runtime Dev
+  description: |-
+    This PR removes the `transfer` syscall and changes balance transfers to make the existential deposit (ED) fully transparent for contracts.
+
+    The `transfer` API is removed since there is no corresponding EVM opcode and transferring via a call introduces barely any overhead.
+
+    We make the ED transparent to contracts by transferring the ED from the call origin to nonexistent accounts. Without this change, transfers to nonexistant accounts will transfer the supplied value minus the ED from the contracts viewpoint, and consequentially fail if the supplied value lies below the ED. Changing this behavior removes the need for contract code to handle this rather annoying corner case and aligns better with the EVM. The EVM charges a similar deposit from the gas meter, so transferring the ED from the call origin is practically the same as the call origin pays for gas.

+title: '[pallet-child-bounties] Index child bounties by parent bounty'
+doc:
+- audience: Runtime Dev
+  description: |
+    Index child bounties by their parent bounty, ensuring that their indexes are independent of
+    child bounties from other parent bounties. This will allow for predictable indexes and the
+    ability to batch creation and approval calls together.
+
+    ### Migration for Runtime Pallet Instance
+    Use `migration::v1::MigrateToV1Impl` storage migration type to translate ids for the active
+    child bounties and migrate the state to the new schema.
+
+    ### Migration for Clients
+    - Use new `ParentTotalChildBounties` storage item to iterate over child bounties for a certain
+    parent bounty;
+    - Use new `ChildBountyDescriptionsV1` storage item to get the bounty description instead of
+    removed `ChildBountyDescriptions`;
+    - Use `V0ToV1ChildBountyIds` storage item to look up the new child bounty id for a given 
+    old child bounty id;
+    - Update the child bounty account id derivation from `PalletId + "cb" + child_id` to
+    `PalletId + "cb" + bounty_id + child_id`.
+
+    ### Additional Notes
+    - The `ChildBountyCount` storage item is deprecated and will be remove in May 2025.

+    description: |
+      This PR populates the authority DHT records with public listen addresses if any.
+      The change effectively ensures that addresses are added to the DHT record in the
+      following order:
+        1. Public addresses provided by CLI `--public-addresses`
+        2. Maximum of 4 public (global) listen addresses (if any)
+        3. Any external addresses discovered from the network (ie from `/identify` protocol)
+      
+      While at it, this PR adds the following constraints on the number of addresses:
+       - Total number of addresses cached is bounded at 16 (increased from 10).
+       - A maximum number of 32 addresses are published to DHT records (previously unbounded).
+       - A maximum of 4 global listen addresses are utilized.
+      
+      This PR replaces the following warning:
+      `WARNING: No public address specified, validator node may not be reachable.`
+      with a more descriptive one originated from the authority-discovery

+title: XCMv5 - Add ExecuteWithOrigin instruction
+
+doc:
+  - audience: [Runtime User, Runtime Dev]
+    description: |
+      Added a new instruction to XCMv5, ExecuteWithOrigin, that allows you to specify an interior origin
+      and a set of instructions that will be executed using that origin.
+      The origins you can choose are `None` to clear it during the execution of the inner instructions,
+      or `Some(InteriorLocation)` to descend into an interior location.
+      These two options mimic the behaviour of `ClearOrigin` and `DescendOrigin` respectively.
+      Crucially, this instruction goes back to the previous origin once the execution of those inner
+      instructions end.
+      This allows use-cases like a parent location paying fees with one interior location, fetching funds
+      with another, claiming assets on behalf of many different ones, etc.

+title: Remove network starter that is no longer needed
+doc:
+- audience: Node Dev
+  description: |-
+    # Description
+
+    This seems to be an old artifact of the long closed https://github.com/paritytech/substrate/issues/6827 that I noticed when working on related code earlier.
+
+    ## Integration
+
+    `NetworkStarter` was removed, simply remove its usage:
+    ```diff
+    -let (network, system_rpc_tx, tx_handler_controller, start_network, sync_service) =
+    +let (network, system_rpc_tx, tx_handler_controller, sync_service) =
+        build_network(BuildNetworkParams {
+    ...
+    -start_network.start_network();
+    ```
+
+    ## Review Notes
+
+    Changes are trivial, the only reason for this to not be accepted is if it is desired to not start network automatically for whatever reason, in which case the description of network starter needs to change.
+

+title: 'frame-benchmarking: Use correct components for pallet instances'
+doc:
+- audience: Runtime Dev
+  description: |-
+    When benchmarking multiple instances of the same pallet, each instance was executed with the components of all instances. While actually each instance should only be executed with the components generated for the particular instance. The problem here was that in the runtime only the pallet-name was used to determine if a certain pallet should be benchmarked. When using instances, the pallet name is the same for both of these instances. The solution is to also take the instance name into account.
+
+    The fix requires to change the `Benchmark` runtime api to also take the `instance`. The node side is written in a backwards compatible way to also support runtimes which do not yet support the `instance` parameter.

+doc:
+- audience: Runtime Dev

+    There is no need to verify in the `pallet-membership` benchmark that the `MemembershipChanged` implementation works as the pallet thinks it should work. If you for example set it to `()`, `get_prime()` will always return `None`.
+
+    TLDR: Remove the checks of `MembershipChanged` in the benchmarks to support any kind of implementation.

+# Chain Spec Builder
+
+Substrate's chain spec builder utility.
+
+A chain-spec is short for `chain-specification`. See the [`sc-chain-spec`](https://crates.io/docs.rs/sc-chain-spec/latest/sc_chain_spec)
+for more information.
+
+_Note:_ this binary is a more flexible alternative to the `build-spec` subcommand, contained in typical Substrate-based nodes.
+This particular binary is capable of interacting with [`sp-genesis-builder`](https://docs.rs/sp-genesis-builder/latest/sp_genesis_builder/index.html)
+implementation of any provided runtime allowing to build chain-spec JSON files.
+
+See [`ChainSpecBuilderCmd`](https://docs.rs/staging-chain-spec-builder/6.0.0/staging_chain_spec_builder/enum.ChainSpecBuilderCmd.html)
+for a list of available commands.
+
+## Installation
+
+```bash
+cargo install staging-chain-spec-builder
+```
+
+_Note:_ `chain-spec-builder` binary is published on [crates.io](https://crates.io) under
+[`staging-chain-spec-builder`](https://crates.io/crates/staging-chain-spec-builder) due to a name conflict.
+
+## Usage
+
+Please note that below usage is backed by integration tests. The commands' examples are wrapped
+around by the `bash!(...)` macro calls.
+
+### Generate chains-spec using default config from runtime
+
+Query the default genesis config from the provided runtime WASM blob and use it in the chain spec.
+
+<!-- docify::embed!("tests/test.rs", cmd_create_default) -->
+
+_Note:_ [`GenesisBuilder::get_preset`](https://docs.rs/sp-genesis-builder/latest/sp_genesis_builder/trait.GenesisBuilder.html#method.get_preset)
+runtime function is called.
+
+### Display the runtime's default `GenesisConfig`
+
+<!-- docify::embed!("tests/test.rs", cmd_display_default_preset) -->
+
+_Note:_ [`GenesisBuilder::get_preset`](https://docs.rs/sp-genesis-builder/latest/sp_genesis_builder/trait.GenesisBuilder.html#method.get_preset)
+runtime function is called.
+
+### Display the `GenesisConfig` preset with given name
+
+<!-- docify::embed!("tests/test.rs", cmd_display_preset)-->
+
+_Note:_ [`GenesisBuilder::get_preset`](https://docs.rs/sp-genesis-builder/latest/sp_genesis_builder/trait.GenesisBuilder.html#method.get_preset)
+runtime function is called.
+
+### List the names of `GenesisConfig` presets provided by runtime
+
+<!-- docify::embed!("tests/test.rs", cmd_list_presets)-->
+
+_Note:_ [`GenesisBuilder::preset_names`](https://docs.rs/sp-genesis-builder/latest/sp_genesis_builder/trait.GenesisBuilder.html#method.preset_names)
+runtime function is called.
+
+### Generate chain spec using runtime provided genesis config preset
+
+Patch the runtime's default genesis config with the named preset provided by the runtime and generate the plain
+version of chain spec:
+
+<!-- docify::embed!("tests/test.rs", cmd_create_with_named_preset)-->
+
+_Note:_ [`GenesisBuilder::get_preset`](https://docs.rs/sp-genesis-builder/latest/sp_genesis_builder/trait.GenesisBuilder.html#method.get_preset)
+runtime functions are called.
+
+### Generate raw storage chain spec using genesis config patch
+
+Patch the runtime's default genesis config with provided `patch.json` and generate raw
+storage (`-s`) version of chain spec:
+
+<!-- docify::embed!("tests/test.rs", cmd_create_with_patch_raw)-->
+
+Refer to [*patch file*](#patch-file) for some details on the patch file format.
+
+_Note:_ [`GenesisBuilder::get_preset`](https://docs.rs/sp-genesis-builder/latest/sp_genesis_builder/trait.GenesisBuilder.html#method.get_preset)
+and
+[`GenesisBuilder::build_state`](https://docs.rs/sp-genesis-builder/latest/sp_genesis_builder/trait.GenesisBuilder.html#method.build_state)
+runtime functions are called.
+
+### Generate raw storage chain spec using full genesis config
+
+Build the chain spec using provided full genesis config json file. No defaults will be used:
+
+<!-- docify::embed!("tests/test.rs", cmd_create_full_raw)-->
+
+Refer to [*full config file*](#full-genesis-config-file) for some details on the full file format.
+
+_Note_: [`GenesisBuilder::build_state`](https://docs.rs/sp-genesis-builder/latest/sp_genesis_builder/trait.GenesisBuilder.html#method.build_state)
+runtime function is called.
+

+This section provides details on the files that can be used with `create patch` or `create full` subcommands.
+
+### Patch file
+The patch file for genesis config contains the key-value pairs valid for given runtime, that needs to be customized,
+	e.g:
+```ignore
+{
+	"balances": {
+		"balances": [
+			[
+				"5FHneW46xGXgs5mUiveU4sbTyGBzmstUspZC92UhjJM694ty",
+			    1000000000000000
+			],
+			[
+				"5FLSigC9HGRKVhB9FiEo4Y3koPsNmBmLJbpXg2mp1hXcS59Y",
+			     1000000000000000
+			],
+			[
+				"5CcjiSgG2KLuKAsqkE2Nak1S2FbAcMr5SxRASUuwR3zSNV2b",
+			    5000000000000000
+			]
+		]
+	},
+	"sudo": {
+		"key": "5Ff3iXP75ruzroPWRP2FYBHWnmGGBSb63857BgnzCoXNxfPo"
+	}
+}
+```
+The rest of genesis config keys will be initialized with default values.
+
+### Full genesis config file
+The full genesis config file must contain values for *all* the keys present in the genesis config for given runtime. The
+format of the file is similar to patch format. Example is not provided here as it heavily depends on the runtime.
+
+### Extra tools
+
+The `chain-spec-builder` provides also some extra utilities: [`VerifyCmd`](https://docs.rs/staging-chain-spec-builder/latest/staging_chain_spec_builder/struct.VerifyCmd.html),
+[`ConvertToRawCmd`](https://docs.rs/staging-chain-spec-builder/latest/staging_chain_spec_builder/struct.ConvertToRawCmd.html),

+# Chain Spec Builder
+
+Substrate's chain spec builder utility.
+
+A chain-spec is short for `chain-specification`. See the [`sc-chain-spec`](https://crates.io/docs.rs/sc-chain-spec/latest/sc_chain_spec)
+for more information.
+
+_Note:_ this binary is a more flexible alternative to the `build-spec` subcommand, contained in typical Substrate-based nodes.
+This particular binary is capable of interacting with [`sp-genesis-builder`](https://docs.rs/sp-genesis-builder/latest/sp_genesis_builder/index.html)
+implementation of any provided runtime allowing to build chain-spec JSON files.
+
+See [`ChainSpecBuilderCmd`](https://docs.rs/staging-chain-spec-builder/6.0.0/staging_chain_spec_builder/enum.ChainSpecBuilderCmd.html)
+for a list of available commands.
+
+## Installation
+
+```bash
+cargo install staging-chain-spec-builder
+```
+
+_Note:_ `chain-spec-builder` binary is published on [crates.io](https://crates.io) under
+[`staging-chain-spec-builder`](https://crates.io/crates/staging-chain-spec-builder) due to a name conflict.
+
+## Usage
+
+Please note that below usage is backed by integration tests. The commands' examples are wrapped
+around by the `bash!(...)` macro calls.
+
+### Generate chains-spec using default config from runtime
+
+Query the default genesis config from the provided runtime WASM blob and use it in the chain spec.
+
+```rust,ignore
+bash!(
+	chain-spec-builder -c "/dev/stdout" create -r $runtime_path default
+)
+```
+
+_Note:_ [`GenesisBuilder::get_preset`](https://docs.rs/sp-genesis-builder/latest/sp_genesis_builder/trait.GenesisBuilder.html#method.get_preset)
+runtime function is called.
+
+### Display the runtime's default `GenesisConfig`
+
+```rust,ignore
+bash!(
+	chain-spec-builder display-preset -r $runtime_path
+)
+```
+
+_Note:_ [`GenesisBuilder::get_preset`](https://docs.rs/sp-genesis-builder/latest/sp_genesis_builder/trait.GenesisBuilder.html#method.get_preset)
+runtime function is called.
+
+### Display the `GenesisConfig` preset with given name
+
+```rust,ignore
+fn cmd_display_preset(runtime_path: &str) -> String {
+	bash!(
+		chain-spec-builder display-preset -r $runtime_path -p "staging"
+	)
+}
+```
+
+_Note:_ [`GenesisBuilder::get_preset`](https://docs.rs/sp-genesis-builder/latest/sp_genesis_builder/trait.GenesisBuilder.html#method.get_preset)
+runtime function is called.
+
+### List the names of `GenesisConfig` presets provided by runtime
+
+```rust,ignore
+bash!(
+	chain-spec-builder list-presets -r $runtime_path
+)
+```
+
+_Note:_ [`GenesisBuilder::preset_names`](https://docs.rs/sp-genesis-builder/latest/sp_genesis_builder/trait.GenesisBuilder.html#method.preset_names)
+runtime function is called.
+
+### Generate chain spec using runtime provided genesis config preset
+
+Patch the runtime's default genesis config with the named preset provided by the runtime and generate the plain
+version of chain spec:
+
+```rust,ignore
+bash!(
+	chain-spec-builder -c "/dev/stdout" create --relay-chain "dev" --para-id 1000 -r $runtime_path named-preset "staging"
+)
+```
+
+_Note:_ [`GenesisBuilder::get_preset`](https://docs.rs/sp-genesis-builder/latest/sp_genesis_builder/trait.GenesisBuilder.html#method.get_preset)
+runtime functions are called.
+
+### Generate raw storage chain spec using genesis config patch
+
+Patch the runtime's default genesis config with provided `patch.json` and generate raw
+storage (`-s`) version of chain spec:
+
+```rust,ignore
+bash!(
+	chain-spec-builder -c "/dev/stdout" create -s -r $runtime_path patch "tests/input/patch.json"
+)
+```
+
+Refer to [*patch file*](#patch-file) for some details on the patch file format.
+
+_Note:_ [`GenesisBuilder::get_preset`](https://docs.rs/sp-genesis-builder/latest/sp_genesis_builder/trait.GenesisBuilder.html#method.get_preset)
+and
+[`GenesisBuilder::build_state`](https://docs.rs/sp-genesis-builder/latest/sp_genesis_builder/trait.GenesisBuilder.html#method.build_state)
+runtime functions are called.
+
+### Generate raw storage chain spec using full genesis config
+
+Build the chain spec using provided full genesis config json file. No defaults will be used:
+
+```rust,ignore
+bash!(
+	chain-spec-builder -c "/dev/stdout" create -s -r $runtime_path full "tests/input/full.json"
+)
+```
+
+Refer to [*full config file*](#full-genesis-config-file) for some details on the full file format.
+
+_Note_: [`GenesisBuilder::build_state`](https://docs.rs/sp-genesis-builder/latest/sp_genesis_builder/trait.GenesisBuilder.html#method.build_state)
+runtime function is called.
+
+### Generate human readable chain spec using provided genesis config patch
+
+```rust,ignore
+bash!(
+	chain-spec-builder -c "/dev/stdout" create -r $runtime_path patch "tests/input/patch.json"
+)
+```
+
+Refer to [*patch file*](#patch-file) for some details on the patch file format.
+
+### Generate human readable chain spec using provided full genesis config
+

+)
+```
+
+Refer to [*full config file*](#full-genesis-config-file) for some details on the full file format.

 ### Configure MetaMask
 
-You can use the following instructions to setup [MetaMask] with the local chain.
+See the doc [here](https://contracts.polkadot.io/work-with-a-local-node#metemask-configuration) for more
+information on how to configure MetaMask.
 
-> **Note**: When you interact with MetaMask and restart the chain, you need to clear the activity tab (Settings >
-Advanced > Clear activity tab data), and in some cases lock/unlock MetaMask to reset the nonce.
-See [this guide][reset-account] for more info on how to reset the account activity.
-
-#### Add a new network
-
-To interact with the local chain, add a new network in [MetaMask].
-See [this guide][add-network] for more info on how to add a custom network.
-
-Make sure the node and the RPC server are started, and use the following settings to configure the network
-(MetaMask > Networks > Add a network manually):
-
-- Network name: KitchenSink
-- RPC URL: <http://localhost:8545>
-- Chain ID: 420420420
-- Currency Symbol: `DEV`
-
-#### Import Dev account
-
-You will need to import the following account, endowed with some balance at genesis, to interact with the chain.
-See [this guide][import-account] for more info on how to import an account.
-
-- Account: `0xf24FF3a9CF04c71Dbc94D0b566f7A27B94566cac`
-- Private Key: `5fb92d6e98884f76de468fa3f6278f8807c48bebc13595d45af5bdc4da702133`

+## Starting a Minimal Template Chain
+
+### Omni Node
+
+[Omni Node](https://paritytech.github.io/polkadot-sdk/master/polkadot_sdk_docs/reference_docs/omni_node/index.html) can
+be used to run the minimal template's runtime. `polkadot-omni-node` binary crate usage is described at a high-level
+[on crates.io](https://crates.io/crates/polkadot-omni-node).
+
+#### Install `polkadot-omni-node`
+
+Please see installation section on [crates.io/omni-node](https://crates.io/crates/polkadot-omni-node).
+
+#### Build `minimal-template-runtime`
+
+```sh
+cargo build -p minimal-template-runtime --release
+```
+
+#### Install `staging-chain-spec-builder`
 
-🔨 Use the following command to build the node without launching it:
+Please see the installation section at [`crates.io/staging-chain-spec-builder`](https://crates.io/crates/staging-chain-spec-builder).
+
+#### Use chain-spec-builder to generate the chain_spec.json file
 
 ```sh
-cargo build --release
+chain-spec-builder create --relay-chain "dev" --para-id 1000 --runtime \
+    target/release/wbuild/minimal-template-runtime/minimal_template_runtime.wasm named-preset development
 ```
 
-🐳 Alternatively, build the docker image:
+**Note**: the `relay-chain` and `para-id` flags are extra bits of information required to
+configure the node for the case of representing a parachain that is connected to a relay chain.
+They are not relevant to minimal template business logic, but they are mandatory information for
+Omni Node, nonetheless.
+
+#### Run Omni Node
+
+Start Omni Node with manual seal (3 seconds block times), minimal template runtime based
+chain spec. We'll use `--tmp` flag to start the node with its configurations stored in a
+temporary directory, which will be deleted at the end of the process.
+
+```sh
+polkadot-omni-node --chain <path/to/chain_spec.json> --dev-block-time 3000 --tmp
+```
+
+### Minimal Template Node
+
+#### Build both node & runtime
+
+```sh
+cargo build --workspace --release
+```
+
+🐳 Alternatively, build the docker image which builds all the workspace members,
+and has as entry point the node binary:
 
 ```sh
 docker build . -t polkadot-sdk-minimal-template
 ```
 
-### Single-Node Development Chain
+#### Start the `minimal-template-node`
 
-👤 The following command starts a single-node development chain:
+The `minimal-template-node` has dependency on the `minimal-template-runtime`. It will use
+the `minimal_template_runtime::WASM_BINARY` constant (which holds the WASM blob as a byte
+array) for chain spec building, while starting. This is in contrast to Omni Node which doesn't
+depend on a specific runtime, but asks for the chain spec at startup.
 
 ```sh
-./target/release/minimal-template-node --dev
+<target/release/path/to/minimal-template-node> --tmp --consensus manual-seal-3000
+# or via docker
+docker run --rm polkadot-sdk-minimal-template
+```
+
+### Zombienet with Omni Node
+
+#### Install `zombienet`
+
+We can install `zombienet` as described [here](https://paritytech.github.io/zombienet/install.html#installation),
+and `zombienet-omni-node.toml` contains the network specification we want to start.
+
+#### Update `zombienet-omni-node.toml` with a valid chain spec path
+
+Before starting the network with zombienet we must update the network specification
+with a valid chain spec path. If we need to generate one, we can look up at the previous
+section for chain spec creation [here](#use-chain-spec-builder-to-generate-the-chain_specjson-file).
 
-# docker version:
-docker run --rm polkadot-sdk-minimal-template --dev
+Then make the changes in the network specification like so:
+
+```toml
+# ...
+chain = "dev"
+chain_spec_path = "<TO BE UPDATED WITH A VALID PATH>"
+default_args = ["--dev-block-time 3000"]
+# ..
+```
+
+#### Start the network
+
+```sh
+zombienet --provider native spawn zombienet-omni-node.toml
 ```

+
+Previously minimal template's development chains:
+
+- ❌ Started in a multi-node setup will produce forks because minimal lacks consensus.
+- 🧹 Do not persist the state.
+- 💰 Are pre-configured with a genesis state that includes several pre-funded development accounts.
+- 🧑‍⚖️ One development account (`ALICE`) is used as `sudo` accounts.

-### Build
+## Starting a Development Chain
+
+### Omni Node Prerequisites
 
-🔨 Use the following command to build the node without launching it:
+[Omni Node](https://paritytech.github.io/polkadot-sdk/master/polkadot_sdk_docs/reference_docs/omni_node/index.html) can
+be used to run the parachain template's runtime. `polkadot-omni-node` binary crate usage is described at a high-level
+[on crates.io](https://crates.io/crates/polkadot-omni-node).
+
+#### Install `polkadot-omni-node`
+
+Please see the installation section at [`crates.io/omni-node`](https://crates.io/crates/polkadot-omni-node).
+
+#### Build `parachain-template-runtime`
 
 ```sh
 cargo build --release
 ```
 
-🐳 Alternatively, build the docker image:
+#### Install `staging-chain-spec-builder`
+
+Please see the installation section at [`crates.io/staging-chain-spec-builder`](https://crates.io/crates/staging-chain-spec-builder).
+
+#### Use `chain-spec-builder` to generate the `chain_spec.json` file
 
 ```sh
-docker build . -t polkadot-sdk-parachain-template
+chain-spec-builder create --relay-chain "rococo-local" --para-id 1000 --runtime \
+    target/release/wbuild/parachain-template-runtime/parachain_template_runtime.wasm named-preset development
 ```
 
-### Local Development Chain
+**Note**: the `relay-chain` and `para-id` flags are mandatory information required by
+Omni Node, and for parachain template case the value for `para-id` must be set to `1000`, since this
+is also the value injected through [ParachainInfo](https://docs.rs/staging-parachain-info/0.17.0/staging_parachain_info/)
+pallet into the `parachain-template-runtime`'s storage. The `relay-chain` value is set in accordance
+with the relay chain ID where this instantiation of parachain-template will connect to.
 
-🧟 This project uses [Zombienet](https://github.com/paritytech/zombienet) to orchestrate the relaychain and parachain nodes.
-You can grab a [released binary](https://github.com/paritytech/zombienet/releases/latest) or use an [npm version](https://www.npmjs.com/package/@zombienet/cli).
+#### Run Omni Node
 
-This template produces a parachain node.
-You can install it in your environment by running:
+Start Omni Node with the generated chain spec. We'll start it development mode (without a relay chain config),
+with a temporary directory for configuration (given `--tmp`), and block production set to create a block with
+every second.
+
+```bash
+polkadot-omni-node --chain <path/to/chain_spec.json> --tmp --dev-block-time 1000
 
-```sh
-cargo install --path node
 ```
 
-You still need a relaychain node - you can download the `polkadot`
-(and the accompanying `polkadot-prepare-worker` and `polkadot-execute-worker`)
-binaries from [Polkadot SDK releases](https://github.com/paritytech/polkadot-sdk/releases/latest).
+However, such a setup is not close to what would run in production, and for that we need to setup a local
+relay chain network that will help with the block finalization. In this guide we'll setup a local relay chain
+as well. We'll not do it manually, by starting one node at a time, but we'll use [zombienet](https://paritytech.github.io/zombienet/intro.html).
+
+Follow through the next section for more details on how to do it.
 
-In addition to the installed parachain node, make sure to bring
-`zombienet`, `polkadot`, `polkadot-prepare-worker`, and `polkadot-execute-worker`
-into `PATH`, for example:
+### Zombienet setup with Omni Node
+
+Assuming we continue from the last step of the previous section, we have a chain spec and we need to setup a relay chain.
+We can install `zombienet` as described [here](https://paritytech.github.io/zombienet/install.html#installation), and
+`zombienet-omni-node.toml` contains the network specification we want to start.
+
+#### Relay chain prerequisites
+
+Download the `polkadot` (and the accompanying `polkadot-prepare-worker` and `polkadot-execute-worker`) binaries from
+[Polkadot SDK releases](https://github.com/paritytech/polkadot-sdk/releases). Then expose them on `PATH` like so:
 
 ```sh
-export PATH="<path-to-binaries>:$PATH"
+export PATH="$PATH:<path/to/binaries>"
 ```
 
-This way, we can conveniently use them in the following steps.
+#### Update `zombienet-omni-node.toml` with a valid chain spec path
+
+```toml
+# ...
+[[parachains]]
+id = 1000
+chain_spec_path = "<TO BE UPDATED WITH A VALID PATH>"
+# ...
+```
 
-👥 The following command starts a local development chain, with a single relay chain node and a single parachain collator:
+#### Start the network
 
 ```sh
-zombienet --provider native spawn ./zombienet.toml
+zombienet --provider native spawn zombienet-omni-node.toml
+```
+
+### Parachain Template Node
+
+As mentioned in the `Template Structure` section, the `node` crate is optionally compiled and it is an alternative
+to `Omni Node`. Similarly, it requires setting up a relay chain, and we'll use `zombienet` once more.
+
+#### Install the `parachain-template-node`
 
-# Alternatively, the npm version:
-npx --yes @zombienet/cli --provider native spawn ./zombienet.toml
+```sh
+cargo install --path node
 ```
 
-Development chains:
+#### Setup and start the network
+
+For setup, please consider the instructions for `zombienet` installation [here](https://paritytech.github.io/zombienet/install.html#installation)
+and [relay chain prerequisites](#relay-chain-prerequisites).
 
-* 🧹 Do not persist the state.
-* 💰 Are preconfigured with a genesis state that includes several prefunded development accounts.

+//! parachain tests supported for now).
+//!
+//! You can run the following command to generate a minimal chainspec, once the runtime wasm file is

+//!`chain-spec-builder create --relay-chain <relay_chain_id> --para-id 1000 -r \
+//!     <path_to_template_wasm_file> named-preset development`
+//!
+//! Once the files are generated, you must export an environment variable called
+//! `CHAIN_SPECS_DIR` which should point to the absolute path of the directory
+//! that holds the generated chain specs. The chain specs file names should be
+//! `minimal_chain_spec.json` for minimal and `parachain_chain_spec.json` for parachain
+//! templates.
+//!
+//! To start all tests here we should run:
