+## Update Your Extension
+
+When developing/updating your extension, you will likely need to update its content from its submodule in the extensions repository.
+To quickly fetch the latest code for only specific extension (and avoid updating all others), use the specific path:
+
+```sh
+# From the root of the repository:
+git submodule update --remote extensions/your-extension-name
+```
+
+> Note: If you need to update all submodules (e.g., if multiple extensions have changed, or for a full clean build), you can run `git submodule update` without a path, but this will take longer.

 ## Extension License Requirements
