@virtually-stray Thanks your PR, this is a good start! There's a small question, if you only modify README, you need to change the type in the PR title from feat(docs) to docs. More see Commit Message Format. The PR title will be used as a merging commit message.

And like many open-source projects, we ask that you sign our Contributor License Agreement before we can accept your contribution. You just need to reply to I have read the CLA Document and I hereby sign the CLA in PR.

Sorry for the mistake. It won't happen again.

I've signed the agreement and changed the PR title to docs type. I've also changed the /kind to documentation. If there's any other change needed, please, let me know.
