+
+Introduction
+------------
+
+By design asyncio `does not allow <https://github.com/python/cpython/issues/66435>`_
+its event loop to be nested. This presents a practical problem:
+When in an environment where the event loop is
+already running it's impossible to run tasks and wait
+for the result. Trying to do so will give the error
+"``RuntimeError: This event loop is already running``".
+
+The issue pops up in various environments, such as web servers,
+GUI applications and in Jupyter notebooks.
+
+This module patches asyncio to allow nested use of ``asyncio.run`` and
+``loop.run_until_complete``.
+
+Installation
+------------
+
+.. code-block::
+
+    pip3 install nest_asyncio
+
+Python 3.5 or higher is required.
+
+Usage
+-----
+
+.. code-block:: python
+
+    import nest_asyncio
+    nest_asyncio.apply()
+
+Optionally the specific loop that needs patching can be given
+as argument to ``apply``, otherwise the current event loop is used.
+An event loop can be patched whether it is already running
+or not. Only event loops from asyncio can be patched;
+Loops from other projects, such as uvloop or quamash,
+generally can't be patched.
