+While this is primarily an personal project for my NixOS setup, community contributions are welcome, especially at utility tooling I wrote in the `misc` directory (e.g.

+
+## Prerequisites
+
+Other than the regular "review and agree to the [Community Code of Conduct][ccoc] and [the Linux DCO][dco]",
+
+* Hands-on experience with writing Nix configs for NixOS/home-manager (vibe coding/Gen AI is fine, just make sure to review the outputs before submitting a patch) and shell scripting (mainly Bash)
