## ⚡ Quickstart
If you want to get an example node running quickly you can execute the following getting started script:
```
curl --proto '=https' --tlsv1.2 -sSf https://raw.githubusercontent.com/paritytech/polkadot-sdk/master/scripts/getting-started.sh | bash

* [Introduction](https://paritytech.github.io/polkadot-sdk/master/polkadot_sdk_docs/polkadot_sdk/index.html)
to each component of the Polkadot SDK: Substrate, FRAME, Cumulus, and XCM
* [Guides](https://paritytech.github.io/polkadot-sdk/master/polkadot_sdk_docs/guides/index.html),
namely how to build your first FRAME pallet.

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](docs/RELEASE.md).
You can use [`psvm`](https://github.com/paritytech/psvm) to manage your Polkadot-SDK dependency
versions in downstream projects.
`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` 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`.
## 🛠️ Tooling
[Polkadot SDK Version Manager](https://github.com/paritytech/psvm):
A simple tool to manage and update the Polkadot SDK dependencies in any Cargo.toml file.
It will automatically update the Polkadot SDK dependencies to their correct crates.io version.
The security policy and procedures can be found in

Development in this repo usually goes hand in hand with the `fellowship` organization. In short,
this repository provides all the SDK pieces needed to build both Polkadot and its parachains. But,
the actual Polkadot runtime lives in the `fellowship/runtimes` repository. Read more about the
fellowship, this separation, the RFC process
[here](https://polkadot-fellows.github.io/dashboard/).
This repository is the amalgamation of 3 separate repositories that used to make up Polkadot SDK,
namely Substrate, Polkadot and Cumulus. Read more about the merge and its history
