    General guidance from repository metadata, not legal advice. How we score

    From the README

    This repository contains Bluesky's reference implementation of AT Protocol, and of the app.bsky microblogging application service backend.

    Lexicons: for both the com.atproto.* and app.bsky.* are canonically versioned in this repo, for now, under ./lexicons/. These are JSON files in the Lexicon schema definition language, similar to JSON Schema or OpenAPI.

    Interoperability Test Data: the language-neutral test files in ./interop-test-files/ may be useful for other protocol implementations to ensure that they follow the specification correctly

    The source code for the Bluesky Social client app (for web and mobile) can be found at bluesky-social/social-app.

    Go programming language source code is in bluesky-social/indigo, including the BGS implementation.

    We recommend nvm for managing Node.js installs. This project requires Node.js version 18. pnpm is used to manage the workspace of multiple packages. You can install it with npm install --global pnpm.
