+Integration With Starlette-based Frameworks
+===========================================
+
+This is a `Starlette <https://www.starlette.io/>`_ +
+`Dependency Injector <https://python-dependency-injector.ets-labs.org/>`_ example application
+utilizing `lifespan API <https://www.starlette.io/lifespan/>`_.
+
+.. note::
+
+    Pretty much `any framework built on top of Starlette <https://www.starlette.io/third-party-packages/#frameworks>`_
+    supports this feature (`FastAPI <https://fastapi.tiangolo.com/advanced/events/#lifespan>`_,
+    `Xpresso <https://xpresso-api.dev/latest/tutorial/lifespan/>`_, etc...).
+
+Run
+---
+
+Create virtual environment:
+
+.. code-block:: bash
+
+    python -m venv env
+    . env/bin/activate
+
+Install requirements:
+
+.. code-block:: bash
+
+    pip install -r requirements.txt
+
+To run the application do:
+
+.. code-block:: bash
+
+    python example.py
+    # or (logging won't be configured):
+    uvicorn --factory example:container.app
+
+After that visit http://127.0.0.1:8000/ in your browser or use CLI command (``curl``, ``httpie``,
+etc).
