 # Codeowners
 
-**Codeowners** is a fast, Rust-based CLI for generating and validating [GitHub `CODEOWNERS` files](https://docs.github.com/en/repositories/managing-your-repositorys-settings-and-features/customizing-your-repository/about-code-owners) in large repositories. It supports conventions for Ruby and JavaScript projects, and is a high-performance reimplementation of the [original Ruby CLI](https://github.com/rubyatscale/code_ownership).

-**Why use this tool?**  
-On large projects, `codeowners gv` is _over 10x faster_ than the legacy Ruby implementation:
