• 🧹 Chore (updates to the build process or auxiliary tools and libraries)

📚 Description

Fixed some typos in the documentation and adjusted the descriptions where I saw fit so the "reading flow" is a bit better :)
I checked this draft PR and it seems that my changes do not overlap with it: #495

Also there were some german links that the linter marked as dead or incorrect, I fixed those too.
Resolves #567

Thanks for this! Lots of good changes here.

I made some comments. Most are "non-blocking" and are marked.

For those not marked "non-blocking" reply to me if you disagree. Otherwise, if you find the changes acceptable, go ahead and add them to the PR.

(I should say up front that I'm not an editor. My only "qualification" here is being an anglophone working on Tres/Cientos!)

Thanks again!

@andretchen0 I addressed all your comments since I like the approach of fixing things that only take a minute right away. 🤙🏽

Please have a second look at it, I also rephrased the part with the "in summary". But probably one person of the core team should comment on that point anyway.

Looks good!

I found one more instance of double quotes in TypeScript code.

[andretchen0]

Great! Approved.

@alvarosabu from my side this is ready to go - maybe you or @JaimeTorrealba have a quick look at the sentence in the light-shadows.md and if the meaning of it is correct after my update.

Great thanks for the feedback @JaimeTorrealba , then I resolve the remaining open threads. I just resolved the merge conflict so it would also be ready to merge from my side.
