-As with all good NixOS configurations, Aether is split into *modules* that
-each provide different functionality. These are stored in the `modules/` directory.

-## External Usage
+## Module Checklist
 
-If you use NixOS and are interested in any of these modules, you can import
+- [x] `forgejo.nix` - Code forge
-them for your own config!
+- [ ] `site.nix` - Personal website
-
+- [ ] `mail.nix` - Mail server
-Add this repository as a flake input:
+- [ ] `backup.nix` - Automated backup system
-
+- [ ] `cachix.nix` - Nix build caching
-``` nix
-{
-  inputs.aether.url = "https://git.tokinanpa.dev/toki/aether/archive/main.tar.gz";
-}
-```
-
-Aether modules are then exposed under `nixosModules.<name>` and deployments
-under `nixosModules.deploy-<name>`. You can activate a module by adding it
-to your `imports`:
-
-``` nix
-{
-  imports = with aether.nixosModules; [
-    # Deployment
-    deploy-rpi5
-    # Modules
-    forgejo
-    ssh
-  ];
-
-  # Required by forgejo module
-  aether.domain = "...";
-}
-```
-
-Any number of modules can be activated at once, but activating more than one
-deployment will cause issues, so that should be avoided.
-
-Some modules have options that can be used to configure their effects. If a
-module has options, they can be found in the `options.nix` file inside the
-module directory. More general options used by multiple modules are
-documented in `modules/options.nix`.
