cgit-pink is a maintained fork of cgit that follows upstream git more

This means that individual subtrees of a repository will also have
their READMEs rendered on the about page, for example:
/foo/bar/README.md
Will render on:
/about/foo/bar/
This is useful for monorepo setups in which subtrees represent
individual projects.
