Dagur Ásgeirsson has written a text to fill this gap:
We discuss in some detail the prerequisites for each of the first four chapters of Scholze's "Lectures on Condensed Mathematics". Some proofs are given in more detail or slightly altered, but all the main ideas are the same. In particular, I claim no originality of the results. It is my hope, however, that I have succeded in creating a more accessible presentation of the foundations of condensed mathematics, along with the prerequisites, than has previously been available.
