This allows using existing documentation in the published documentation
without
* moving the existing docs (which would break external links)
* tricks like symlinks that create issues with relative links
Put the api reference files into a subdirectory to avoid polluting the
main docs/ directory.
Include "Installation" and "Instructions for Contributors" in the
published documentation.
