+
+## Commit Message Format
+
+```
+[location/scope]: [subject]
+
+[body]
+
+[footer]
+```
+
+### Locations
+
+The location in a commit message represents where the change affects.
+
+- A host (`Infini-DESKTOP`, etc.)
+- A module (Just use the module name, not including `module` or `functionality` as a prefix, to reduce length)
+- A profile
+- `pkgs`
+- `overlays`
+- Etc.
+
+If affecting multiple locations, separate with a comma.
+If affecting all, use a `*`, like `hosts/*`.
+If in a sub-location, separate with a slash, such as `overlays/patches`.
+
+### Scopes
+
+A scope is an abstract type of location, such as:
+
+- `flake` for `flake.nix` or a flake-wide change
+- `bump` for `flake.lock` updates
