+## Why spaces? I prefer tabs
+
+PEP 8 recommends spaces over tabs, and they are used by most of the Python community.
+_Black_ provides no options to configure the indentation style, and requests for such
+options will not be considered.
+
+However, we recognise that using tabs is an accessibility issue as well. While the
+option will never be added to _Black_, visually impaired developers may find conversion
+tools such as `expand/unexpand` (for Linux) useful when contributing to Python projects.
+A workflow might consist of e.g. setting up appropriate pre-commit and post-merge git
+hooks, and scripting `unexpand` to run after applying _Black_.

+## What is `compiled: yes/no` all about in the version output?
+
+While _Black_ is indeed a pure Python project, we use [mypyc] to compile _Black_ into a
+C Python extension, usually doubling performance. These compiled wheels are available
+for 64-bit versions of Windows, Linux (via the manylinux standard), and macOS across all
+supported CPython versions.
+
+Platforms including musl-based and/or ARM Linux distributions, and ARM Windows are
+currently **not** supported. These platforms will fall back to the slower pure Python
+wheel available on PyPI.
+
+If you are experiencing exceptionally weird issues or even segfaults, you can try
+passing `--no-binary black` to your pip install invocation. This flag excludes all
+wheels (including the pure Python wheel), so this command will use the [sdist].
