Time to #asknostr

I'm working on a txt reference document that I expect to be shared around parts of the community.

Is there an easy way to authenticate it using #nostr and have those interested easily check the authenticity without any other keyshare or infrastructure?

I don't care if others update it and share their version, but I do want a way to say which versions have my official blessing.

I plan to update regularly based on feedback.

I have no interest in building a website for it, just a TXT document for others to spread at will.

I don't want to mess with git or another centralized version control. Just a new plaintext doc for each revision.

It will be long, my current outline is 60 lines.

It is by my nym, not me.

My first thought is just to share a rev# and hash as a simple note when it changes.

Any services like nostr.build support txt files?
