Sorry for my english. Here's what i usually do:
- kanban as read-list and task tracking
- introductive note to a topic with backlinks to other notes (subtopics)
- a directory with all the subtopics notes, backlink to index note.
I don't like atomic notes or Zetelkastenn methods enough, but be sure to check these methods. If you're more visual, then you may use the canva plugin.
The best system is subjective, try different things and find what works for you.
