Introduction to MetaImage

I just installed MetaImage from Setapp to apply my GPX tracks to image data for my mobile workflow—I can do this in Lightroom Classic (which lives on my desktop), but not Lightroom (which lives on my laptop). I was happy to find a polished app I could use rather than the kinda wonky ones I’ve tried before.

I muddled through importing a folder and GPX track, then exporting XMP files that Lightroom can read, but I don’t completely understand what I did. I do IT support for a living, and I’m one of those strange people who actually read manuals; however, I don’t see one anywhere.

I have a simple question: What tutorial is best to start with to get a basic understanding of the app?

Thanks!
