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.

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.
