@flamarion reviewed the doc changes and pushed language updates in a919434. Also took the the opportunity to improve language and formatting across the doc. Please take a look just to make sure I didn't mess up any of your technical info

Also, in 6709253, I fixed that failing Python lint test. Just a heads up that, if you add media like a .png, you have to run nox -e lint locally at the root level of the weave repo to pre-lint the PR for issues that will be flagged by the GH checks. If that command returns any failures, just run it again and it will usually auto fix the issue. You can then push and the linter checks should pass. That being said, if you run into issues in the future, tag me or someone from the Weave eng team and we can help
