I use Confluence for various topics in my PKB. I have sections (spaces) for Recipes I've found or made, Technical internals (network map and connectivity, what did I do to make that Raspberry pi project?, How do I add a new VLAN to this damn router, What's the process for restoring my paperless document server, one off scripts / oneliners I find useful, etc), meat space stuff (hardware/powertools/appliance serial numbers, part numbers, maint schedule, where to buy parts), and my own tracking of college course syllabus (or cert exams) for studying and tracking. Adding my own notes and processes with sources that I obtained the information has been great. Setting up the PKB has been one of the most useful projects I have; now if I can just remember to keep it updated often!
