+
+This whole folder is for the most part just a system to clean up importing
+
+- In files in this (`system_profiles`) directory:
+  - should never import anything from parent directories
+  - can import things from the child directories
+- The `importers` directory:
+  - Should only import things outside (above/parent) of the `system_profiles` directories.
+  - Probably only from the module directory or maybe a future nix-modules directory,
+    this rule is not set in stone yet
+  - should **not** import anything outside of this repository
+- The `components` directory:
+  - Should never import anything from this repository
+  - It can import things from nixpkgs
+  - Should set only basic "system" settings
+    ("system" is not well defined)
