How do we create a song book using Word or text file

We are interested in using Reading App Builder to create a song app. Is there a site we can look to which has instructions on how to create song books.

There’s a video here: (for Scripture App Builder, but the process is the same).

Also, a few pages in the Manual

If you want to add audio, it gets a little challenging with the synchronization, but it is possible.

Thank you for the manual. I had not found it yet. Very helpful.
