As per [RFC 0072](https://github.com/NixOS/rfcs/pull/72), all new documentation content should be written in [CommonMark](https://commonmark.org/) Markdown dialect.

Additionally, the following syntax extensions are currently used:
Additional syntax extensions are available, though not all extensions can be used in NixOS option documentation. The following extensions are currently used:

- []{#ssec-contributing-markup-anchors}
Explicitly defined **anchors** on headings, to allow linking to sections. These should be always used, to ensure the anchors can be linked even when the heading text changes, and to prevent conflicts between [automatically assigned identifiers](https://github.com/jgm/commonmark-hs/blob/master/commonmark-extensions/test/auto_identifiers.md).

If you want to link to a man page, you can use `` {manpage}`nix.conf(5)` ``, which will turn into {manpage}`nix.conf(5)`. The references will turn into links when a mapping exists in {file}`doc/build-aux/pandoc-filters/link-unix-man-references.lua`.

The references will turn into links when a mapping exists in {file}`doc/build-aux/pandoc-filters/link-unix-man-references.lua`.
A few markups for other kinds of literals are also available:

- `` {command}`rm -rfi` `` turns into {command}`rm -rfi`
- `` {option}`networking.useDHCP` `` turns into {option}`networking.useDHCP`
- `` {file}`/etc/passwd` `` turns into {file}`/etc/passwd`

These literal kinds are used mostly in NixOS option documentation.

This syntax is taken from [MyST](https://myst-parser.readthedocs.io/en/latest/syntax/syntax.html#roles-an-in-line-extension-point). Though, the feature originates from [reStructuredText](https://www.sphinx-doc.org/en/master/usage/restructuredtext/roles.html#role-manpage) with slightly different syntax.
