+## Automatic Imports
+
+The `buildClan` function will automatically import modules if a directory named `<CLAN_ROOT>/imports` exists within the Clan. Below are the conditions for importing inventory modules:
+
+- **Inventory Modules**: Modules located in `<CLAN_ROOT>/imports/inventory` will be automatically imported. Note that only inventory-compatible modules can be used in this location. To be compatible, a module must contain a `roles` folder. 
+
+- **Adding a Module**: To add a module, such as `mymodule`, create a dedicated directory at `<CLAN_ROOT>/imports/inventory/mymodule`, ensuring that it includes a `roles` folder.
+
+For further details on creating Clan modules, please refer to the [Authoring Clan Modules](../clanmodules/index.md) section. 
+
+
 ## Manual declaration
 
 Machines can also be added manually under `buildClan`, `clan.*` in flake-parts or via [`inventory`](../manual/inventory.md).
