Website Tutorial needed

I am somehow very confused with the website module application. There are no real tutorials to find and the UI isn’t self explanatory enough to understand.
At this stage I only understand by trial and error that I can create pages in a mix of WYSIWG and sound knowledge of HTML and CSS + PHP.
It would be helpful to have more explanations on a) how to work with more dynamic website options and how to integrate other Dolibarr installations documents.
At this point for me the website module is unfortunately unusable because I feel like a dummy in front of this website UI without further tutorials.
