+## Modules

+You can add additional modules or remove all of them by overriding parameters to the build_systems command:
+
+```nix
+nixosConfigurations =
+    let
+        additionalMods = {
+            nixos = [
+            # your modules
+            ]; home = [
+            # your modules
+            ];
+        }
+        # passing this parameter will override the existing modules
+        mods = {
+            nixos = [];
+            home = [];
+        }
+    in
+    (inputs.dashNix.dashNixLib.build_systems [
+        "system1"
