+Help us improve the Python documentation!
+
+We'll be working on all parts of the documentation, so all and any changes are
+welcome -- from fixing a spelling error to documenting a new feature.
+
+1. Read
+   ['what to expect'](https://pycon.blogspot.com/2025/04/pyconus-sprints.html)
+   for a briefing on what happens at sprints in general. This was written for
+   the PyCon US sprints, but a lot applies here!
+1. Fork and clone the [repository](https://github.com/python/cpython/fork)
+   **before** arriving at the sprints, to get started faster.
+1. Use the
+   [Python Developer's Guide](https://devguide.python.org/documentation/start-documenting/)
+   to set up an environment for contributing to the documentation.
