Thank you both for your help.
I will read through the help (I hadn’t found that yet), and I’ve started making notes.
I’m really looking for a once-and-for-all solution for note keeping. I found Obsidian via a post on HackerNews last week. Previously I’ve used Ulysses, Standard Notes, Simple Note, Apple Notes, and text files in a git repo. Ulysses was the best of all.
I make notes for work, and for my hobbies, and basically just to give myself a crutch to keep organised (my natural thinking preferences are more creative / analytical rather than organised).
I also came across this vault about workflows which looks very helpful.
I will soak all this in.
