Help needed to setup - complete beginner

[sequelsequel]

Hi!
Thank you for this wonderful library, and I believe this is exactly what I was looking for.
I need to create a sql editor on my github pages, but I don't know where to begin.

Is there a guide I can look up to incorporate this in my webpage?

I tried copying the html for the demo on my webpage. It runs the sql query when on the demo webpage, but when run locally, it gets stuck on fetching results.

Thanks!

This does not work on getting the results from the query
