 # Codeowners
+
 This is a CLI tool to generate [GitHub `CODEOWNERS` files](https://docs.github.com/en/repositories/managing-your-repositorys-settings-and-features/customizing-your-repository/about-code-owners) from an existing project assuming certain conventions around file annotations and Ruby/Javascript packages.
 It's also the [oxidation](https://wiki.mozilla.org/Oxidation) of an existing [CLI tool](https://github.com/rubyatscale/code_ownership) written in Ruby.

-### Adoption
-This is an experimental port, use at your own risk and be prepared to fallback to the Ruby implementation if it stops working, if you still wish to adopt it, here are the instructions:
-
-```bash
-# sets up a Rust toolchain
-curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
-
-# Compile and install locally
-gh repo clone rubyatscale/codeowners-rs
-cd codeowners-rs
-cargo install --path .
-
-# Set an environment variable that switches ZP's commit hook to use the globally installed binary
-echo USE_CODEOWNERS_RS=true >> ~/.zshrc
-```
-
