Superseeds https://github.com/paritytech/polkadot-sdk/pull/1245  

This PR is a migration of the
https://github.com/paritytech/substrate/pull/14577.

The PR added associated types (`AddOrigin` & `RemoveOrigin`) to
`Config`. It allows you to decouple types and areas of responsibility,
since at the moment the same types are responsible for adding and
promoting(removing and demoting). This will improve the flexibility of
the pallet configuration.

```
/// The origin required to add a member.
type AddOrigin: EnsureOrigin<Self::RuntimeOrigin, Success = ()>;

/// The origin required to remove a member. The success value indicates the
/// maximum rank *from which* the removal may be.
type RemoveOrigin: EnsureOrigin<Self::RuntimeOrigin, Success = Rank>;
```
To achieve the backward compatibility, the users of the pallet can use
the old type via the new morph:

```
type AddOrigin = MapSuccess<Self::PromoteOrigin, Ignore>;
type RemoveOrigin = Self::DemoteOrigin;
```

NOTE: We have recently made significant changes to our repository structure. In order to streamline our development process and foster better contributions, we have merged three separate repositories Cumulus, Substrate and Polkadot into this repository. Read more about the changes here.

Polkadot SDK

StackExchange

The Polkadot SDK repository provides all the resources needed to start building on the Polkadot network, a multi-chain blockchain platform that enables different blockchains to interoperate and share information in a secure and scalable way. The Polkadot SDK comprises three main pieces of software:

Polkadot

PolkadotForum Polkadot-license

Implementation of a node for the https://polkadot.network in Rust, using the Substrate framework. This directory currently contains runtimes for the Polkadot, Kusama, Westend, and Rococo networks. In the future, these will be relocated to the runtimes repository.

Substrate

SubstrateRustDocs Substrate-license

Substrate is the primary blockchain SDK used by developers to create the parachains that make up the Polkadot network. Additionally, it allows for the development of self-sovereign blockchains that operate completely independently of Polkadot.

Cumulus

CumulusRustDocs Cumulus-license

Cumulus is a set of tools for writing Substrate-based Polkadot parachains.

Releases

[!NOTE]
Our release process is still Work-In-Progress and may not yet reflect the aspired outline here.

The Polkadot-SDK has two release channels: stable and nightly. Production software is advised to only use stable. nightly is meant for tinkerers to try out the latest features. The detailed release process is described in RELEASE.md.

Stable

stable releases have a support duration of three months. In this period, the release will not have any breaking changes. It will receive bug fixes, security fixes, performance fixes and new non-breaking features on a two week cadence.

Nightly

nightly releases are released every night from the master branch, potentially with breaking changes. They have pre-release version numbers in the format major.0.0-nightlyYYMMDD.

Upstream Dependencies

Below are the primary upstream dependencies utilized in this project:

Security

The security policy and procedures can be found in docs/contributor/SECURITY.md.
