Yes, absolutely, that’s why I mentioned it. Best place to start is look through the issues and where you can make the corrections and submit a PR (pull request). Often issues are marked as “good first issue”. Or ping the author in the chatroom and ask how you can help.
Nope, when you create an issue, if it turns out to be a mistake, someone will close it. If you submit a patch, someone will review it. Hit me up if you have problems figuring out how to help.
The easy way would be to hit the edit button (the pen icon) at the top right-hand corner of the file. If you’re looking to learn a bit more about how Git and pull requests on GitHub work, to make it easier to contribute changes spanning multiple files as well, this documentation might be helpful.
And as Jeff said, feel free to give a shout-out if you need additional pointers!
Nothing, that’s it It looks good; once the maintainers take a look and approve and merge it, then it should show up with the next release. Congrats on your first contribution!
