It's a pity that the images used here are annotated and will therefore
not be accessible. At the very least I added alt texts so that some
meaning can be recovered.
Since this page assumes a novice I've went ahead and added some more
explanation to different sections. I'm happy to see them upstreamed to
Codeberg.
