source links in docs

the links to "source" I belive should deep link to the github source for the file. We should make a new link for "improve this doc" that links to the doc mardown. When I click source, i expect to see the file source..

No files or tests are named. Start by locating where the documentation's "source" links are generated, then verify how the documentation Markdown path is available; done means "source" links to the file's GitHub source and a separate "improve this doc" link points to the Markdown document.
