Docs/simple typo fixes

Description/Motivation/Screenshots

This patch fixes some SUPER simple typos in the documentation, it makes it a bit easier to follow and prevents commands from failing. I'm not trying to get this for contributor credit, I literally don't care if someone else just rolls in these changes in another PR.
