+[nvfetcher](https://github.com/berberman/nvfetcher) is used to track our upstream
+sources to use in modules. This allows us to reduce [IFD](https://nixos.wiki/wiki/Import_From_Derivation)
+and auto-update all themes. Most repositories can be specified like so:
+
+```toml
+[program_name]
+src.git = "https://github.com/catppuccin/program_name.git"
+fetch.github = "catppuccin/program_name"
+```
+
+After creating your module, add the options to enable it in `test.nix` under the
+`nodes.machine` attrset. This will allow for your configuration to be tested along
+with the other modules in a VM automatically.
