 # nixos
 
 Nix Flake for my Linux machines running NixOS.
+
+The directory structure can be interpreted as follows:
+
+- [`flake.nix`](./flake.nix): Main entrypoint for the configuration
+- [hosts/*hostname*](./hosts): Host-specific configuration by setting options
+- [modules](./modules): Declarations of options
+- [modules/users/*username*](./modules/users): Since users are dependent on a host machine to exist, they are defined as a module as well
+- [overlays](./overlays): Attribute overrides of Nix Packages
+- [secrets](./secrets): Encrypted files that hold secrets, for example SSH private keys
