We have a full project handbook but it needs to be updated and translated to English - the first few pages are already in the project manual (scroll down in the table of contents on the left side). You can find the full old German version here. Until we have completed the update of the project handbook, feel free to pose any questions in the #projects channel in Slack. If you want to help in the process or are interested in volunteering as a project coordinator (i.e. organizing projects), contact Manuel Neumann (@Manuel) or Frie (@frie) on Slack.
