+Wiring of dynamically imported modules
+--------------------------------------
+
+You can install an import hook that automatically wires containers to the imported modules.
+This is useful when you import modules dynamically.
+
+.. code-block:: python
+
+   import importlib
+
+   from dependency_injector.wiring import register_loader_containers
+
+   from .containers import Container
+
+
+   if __name__ == '__main__':
+       container = Container()
+       register_loader_containers(container)  # <--- installs import hook
+
+       module = importlib.import_module('package.module')
+       module.foo()
+
+You can register multiple containers in the import hook. For doing this call register function
+with multiple containers ``register_loader_containers(container1, container2, ...)``
+or with a single container ``register_loader_containers(container)`` multiple times.
+
+To unregister a container use ``unregister_loader_containers(container)``.
+Wiring module will uninstall the import hook when unregister last container.
