+# Dynamic container
+
+You can dynamically assign providers to container:
+```python
+import datetime
+
+from tests import container
+from that_depends import BaseContainer, providers
+
+
+class DIContainer(BaseContainer):
+    sync_resource: providers.Resource[datetime.datetime]
+    async_resource: providers.AsyncResource[datetime.datetime]
+
+
+DIContainer.sync_resource = providers.Resource(container.create_sync_resource)
+DIContainer.async_resource = providers.AsyncResource(container.create_async_resource)
+```
+
+And than you can use these providers as usual:
+
+```python
+sync_resource = await DIContainer.sync_resource()
+async_resource = await DIContainer.async_resource()
+```
