## Questions

### Is there a Notion version?

Not yet. It's coming; the Obsidian vault is the one you can buy today.

### Do I need plugins?

Every note works with core Obsidian. The log, queue and dashboard tables use the free Dataview community plugin; the README shows how to turn it on.

### How do I get the files?

Right after paying you land on your downloads page, and we email you the same private link. Lost it? [Resend it here](https://mentarium.io/downloads).

### Can I get a refund?

Yes, within 7 days of buying, for any reason. Reply to your order email or write to support@mentarium.io.
