This patch uses mdformat to auto-format markdown documentation.
To support \ for line breaks (which is what mdformat uses), mkdocs now
requires the pymdownx.escapeall extension.
Because of incompatibilities between mdformat (which formats to
CommonMark) and mkdocs (which expects Python-Markdown), there are now
some limitations: no nested lists, multi-paragraph list items, or
admonitions support.
These limitations are acceptable for now, although some of the docs had
to be adjusted to meet them.
This patch adds a document with guidelines for contributing to chasquid.
It includes suggestions for how to ask questions, how to send patches
(and the expectations around them), and documents how the different
branches are used.
Thanks to raspbeguy (https://github.com/raspbeguy) for suggesting this
improvement.
