+You'll find _Black_'s own .flake8 config file is configured like this. Explanation of
+why W503 and E203 are disabled can be found further in this documentation. And if you're
+curious about the reasoning behind B950,
[Bugbear's documentation](https://github.com/PyCQA/flake8-bugbear#opinionated-warnings)
explains it. The tl;dr is "it's like highway speed limits, we won't bother you if you
overdo it by a few km/h".
+**If you're looking for a minimal, black-compatible flake8 configuration:**

+```ini
+[flake8]
+max-line-length = 88
+extend-ignore = E203
+```
+
### Empty lines
_Black_ avoids spurious vertical whitespace. This is in the spirit of PEP 8 which says
a set of comma-separated Python versions, optionally prefixed with `py`. For example,
to request code that is compatible with Python 3.5 and 3.6, set the header to
`py3.5,py3.6`.
+- `X-Diff`: corresponds to the `--diff` command line flag. If present, a diff of the
+ formats will be output.
If any of these headers are set to invalid values, `blackd` returns a `HTTP 400` error
response, mentioning the name of the problematic header in the message body.
The following notable open-source projects trust _Black_ with enforcing a consistent
code style: pytest, tox, Pyramid, Django Channels, Hypothesis, attrs, SQLAlchemy,
Poetry, PyPA applications (Warehouse, Pipenv, virtualenv), pandas, Pillow, every Datadog
-Agent Integration.
+Agent Integration, Home Assistant.
