The CommonMark extension requires the (C) reference implementation of cmark.

&reftitle.install;

The CommonMark extension releases are hosted by PECL and source is hosted on github, the easiest route to installation is the normal PECL route: &url.pecl.package;cmark.

Windows users can download prebuilt release binaries from the PECL website.

Windows users need to take the additional step of adding cmark.dll (distributed with Windows releases) to their `PATH`.
