@cjmyers could someone generate the frame for the documents section for me? Ideally so that I can add "paragraphs" for the main page separately. I struggle with building the structure for the document's page myself. (also, because I cannot compile it on my pc ;-))

@Fontanapink @JMante1 could one of you help Dagmar with this once you have sorted the organization we are going with.
