+# How to import
+
+To import with flakes use
+```nix
+inputs = {
+  polymc.url = "github:PolyMC/PolyMC";
+};
+
+...
+
+nixpkgs.overlays = [ inputs.polymc.overlay ]; ## Within configuration.nix
+```
+
+To import without flakes use channels:
+
+```
+sudo -i nix-channel --add https://github.com/PolyMC/PolyMC/archive/master.tar.gz polymc
+sudo -i nix-channel --update polymc
+```
+add `<polymc>` to imports in your `configuration.nix`
+
+```nix
+imports = [
+  "<polymc>/packages/nix/overlay.nix
+];
+```
