Could you let us know what your path was in looking? I thought the trail from docs.python.org -> packaging.python.org -> the Projects page -> the respective GitHub/BitBucket pages was reasonably clear now (with the length being inherent in the complexity of the problem), but the current arrangements are all still relatively new, so it also doesn't surprise me there are still discoverability problems.
