text: Title: pytest-xdist rtd documentation site problem
  Body: It seems that pytest-xdist documentation rtd website exists but never container docs on it, but searching for xdist docs brings https://readthedocs.org/projects/pytest-xdist amont top results which is confusing.
  
  Apparently @hpk42 @nicoddemus and @RonnyPfannschmidt the the ones listed as admins on RTD. I suspect that removing the project from RTD can sort the problem. As I guess that if nobody bothered to add a sphinx config in so many years it will never happen.
  
  To improve the situation I would also add extra metadata to package to link directly the readme as the Documentation, avoiding further confusions.
