+**The Rust SDK for building [Astrid](https://github.com/astrid-runtime/astrid) capsules.**
 
 In the OS model, this is the standard library for user-space processes. It gives capsule authors safe, typed access to every kernel service: filesystem, IPC, networking, storage, approval, scheduling, and more. Capsule authors depend on `astrid-sdk` and `serde`. Everything else is handled.
