+#### For Nix with Home Manager
+
+You should get a `fetchFromGitHub`-snippet of the current version of the project via `nurl` with the following command:
+
+```bash
+nix run nixpkgs#nurl https://github.com/GitAlias/gitalias/
+> fetchFromGitHub {
+> owner = "GitAlias";
+> repo = "gitalias";
+> rev = "7b941c3abbcee391b6bfc4f8d6b8372064245b49";
+> hash = "sha256-IvHM6mRtoeVm01cUmTkKqjm6/n3Izau89B7MT69Afo0=";
+> }
+```
+
+This snippet can then be used inside your Home Manager configuration like so:
+
+```nix
+# link gitalias.txt from store to
+# $XDG_CONFIG_HOME/gitalias/gitalias.txt
+xdg.configFile = {
+ "gitalias/gitalias.txt".source = pkgs.fetchFromGitHub {
+ # fill with snippet here
+ } + "/gitalias.txt";
+};
+
+# tell git to include gitalias.txt
+programs.git = {
+ enable = true;
+ includes = [
+ { path = "${config.xdg.configHome}/gitalias/gitalias.txt"; }
+ ];
+};
+```
