# Polkadot SDK
 
[](https://substrate.stackexchange.com/)   
> The Polkadot SDK repository provides all the components needed to start building on the
> [Polkadot](https://polkadot.com/) network, a multi-chain blockchain platform that enables
> different blockchains to interoperate and share information in a secure and scalable way.
## ⚡ 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
```

* [🦀 rust-docs](https://paritytech.github.io/polkadot-sdk/master/polkadot_sdk_docs/index.html): Where we keep track of
the API docs of our Rust crates. Includes:
* [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
* [Templates](https://paritytech.github.io/polkadot-sdk/master/polkadot_sdk_docs/polkadot_sdk/templates/index.html)
for starting a new project.

## 🚀 Releases
 
The Polkadot SDK is released every three months as a `Polkadot stableYYMM` release. Each stable release is supported for
one year with patches. See the next upcoming versions in the [Release
Registry](https://github.com/paritytech/release-registry/) and more docs in [RELEASE.md](./docs/RELEASE.md).
You can use [`psvm`](https://github.com/paritytech/psvm) to update all dependencies to a specific
version without needing to manually select the correct version for each crate.
## 🛠️ 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.

## Polkadot Fellowship
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/).
## History
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
[here](https://polkadot-public.notion.site/Polkadot-SDK-FAQ-fbc4cecc2c46443fb37b9eeec2f0d85f).
