tl;dr Find a place for an ultra quickstart for devs on github and/or your website.
As a longtime (10+ years) subscriber to your RSS feed, I finally needed to use datasette.
I went to /datasette.io/ and saw a lot of text and links.
Eventually, I went to github.com/simonw/datasette and found what I need, but it also wasn't immediately obvious.
This is all I was looking for:
uv tool install datasette
datasette my_db.db
