Improving language and clarity

Cristina Pauna requested to merge langec-proof-read into main

Hi @SchulzeSt during today's workshop I familiarized myself with the latest state of this document and read the whole existing content. In doing so, I improved language and clarity. A few questions remain. I will try to attach them to the affected parts of the text, or otherwise put them into the description or comments here.
