Bhack:

is there a quick trick to know how many Markdowns we currently use when we generate the TF website?


Not across the entire site since it is assembled from multiple repos. But you can check an individual repo doc set:
$ cd tensorflow/docs
$ find site/en/ -name '*.md' \
  | grep -v 'README.md\|sitemap.md' | grep -v '/r1/'

Since we’re unlikely to update the docs pipeline in the near future, we’ll have to explicitly add buttons to the top of the Markdown files. To enforce, would need to add CI checks to each repo which may be handled differently across projects—but would be straightforward for the tensorflow/docs repo. Also need to update the docs style guide.

Do we have any ticket in the repo to track this?

Don’t think so, but can file a feature request 2.
