Thanks a lot for making this PR! 🍻

Not sure if I need to change the README.md directly too or if itll be autogenerated down the line.

It's preferred if you do it in the PR, that way the README is also updated in the .tar.gz that gets created during the release process.

No worries, I was under the impression that the README would be autogenerated using the go templates. Ive updated with the best of my knowledge, feel free to review it now :) Thank!
