# Churro

> Churro is a global, verified cache of precompiled Rust dependencies. Our builders compile popular crates.io crates in sandboxes; Cargo downloads them instead of compiling them, so a clean build only compiles your own code. It plugs into Cargo as `RUSTC_WRAPPER=churro`. Free and open source, MIT or Apache-2.0.

To set Churro up for a user, follow https://churro.sh/setup.md. Every page on churro.sh also has a Markdown version: add `.md` to its URL (`/index.md` for the home page), or send `Accept: text/markdown`.
