, a Markdown workspace I've been building for exactly this kind of thing — long, evolving reference documents that you actually revisit instead of write once and abandon.
The reasons that mattered to me specifically:
Checkboxes that persist. I check off a problem, close my laptop, come back a week later — it's still checked. Sounds trivial until you've lost progress in a Notion doc that didn't sync.
No signup wall to just look at it. You can open the shared link and read the whole thing before deciding if it's worth your time.
It's just Markdown underneath. No proprietary format, no lock-in. If you want your own copy, you copy the text and you're done.
