freedom from `pycodestyle` nagging about formatting. You will save time

you're reading. Formatting becomes transparent after a while and you
can focus on the content instead.

+Try it out now using the `Black Playground <https://black.vercel.app>`_.
+
+.. admonition:: Note - this is a beta product
+
+ *Black* is already `successfully used <https://github.com/psf/black#used-by>`_ by
+ many projects, small and big. *Black* has a comprehensive test suite, with efficient
+ parallel tests, our own auto formatting and parallel Continuous Integration runner.
+ However, *Black* is still beta. Things will probably be wonky for a while. This is
+ made explicit by the "Beta" trove classifier, as well as by the "b" in the version
+ number. What this means for you is that **until the formatter becomes stable, you
+ should expect some formatting to change in the future**. That being said, no drastic
+ stylistic changes are planned, mostly responses to bug reports.
- `Black is an early pre-release <usage.html#note-this-tool-is-alpha-quality-at-the-moment>`_.
+ Also, as a safety measure which slows down processing, *Black* will check that the
+ reformatted code still produces a valid AST that is effectively equivalent to the
+ original (see the
+ `Pragmatism <./the_black_code_style/current_style.html#pragmatism>`_
+ section for details). If you're feeling confident, use ``--fast``.
