@MalikaIhle I saw you were making some typo fixes on main. I've moved those edits over to this pull request, and you can keep making edits to this branch with the following steps:

git checkout main
git pull
git fetch
git checkout malikas_typos

^ This will grab the branch and check it out on your computer. You can then add more typo corrections to this PR with the typical git add git commit and git push steps.

I was fixing them on github directly as I was reading. I had not cloned this repo locally.

isn't that what we are expecting readers of our tutorials to do by clicking on 'edit this page' ? (though I suppose for them it would fork and create a pull request, right?)

You are only able to make edits directly onto the main branch because you're an admin, but other readers won't have the rights to do that. They will have to open Pull Requests (but they don't have to fork.)

In either case, it is generally best to collect as many typos/changes like that as possible into a single PR.

More generally, I have a lot of additional changes that will happen to the manual content, many of which will overwrite the existing content. So I wouldn't spend much time on fixing small errors and typos quite yet.
