First PR here :) I did not find special contributor guidelines (apart from the CLA - which is in progress). Let me know if I missed something.
Unsure about adding this change to the docs - I only see 0.8.0 docs, but no upcoming/0.9.0 docs where I could add this.

Don't worry about the docs. I do those periodically. But, if you want to try it, do what is in doc_build/BUILD

bazel build //doc_build:reference
cp bazel-bin/doc_build/reference.md docs/latest.md
git commit -m 'update docs' docs/latest.md

In progress - I need to do this via corporate (I don't expect issues, I just have to wait for approval)

Great. I'll wait for the CLA. Ping this PR when you are ready and I can merge.

Hi @aiuto, got my CLA finally setup :)
PR is rebased and ready-for-review. (sry for the multiple rebases - had to change my author email)
