Help needed to setup - complete beginner

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!

Start by reviewing the demo HTML and the setup needed to run sql.js on GitHub Pages and locally. Clarify the supported incorporation steps and document why the copied demo gets stuck fetching results locally; done means a beginner can follow the guide and understand the local setup.
