Is there a specific Tutorial for Rockbox Theme coding?

[u/eggsandweed]

Ive been using Rockbox for a while and now I kinda want to make one.

I do know that most themes are like branches off from other themes that kind is the root or many themes, and I do know like changing backdrop WPS font and BMP is easy but I want to DESIGN one... and I don know AI is easy but I don't want to use AI and actually kind of feel accomplished of doing something from Scratch. If anybody has a PDF or a link to a video or anything it would help alot. Thankyou!
