Starting Theme Development for One UI

Hello, I develop themes for the MIUI system on Xiaomi devices, and I’m interested in starting to develop themes for the One UI system. However, I’m not sure where to begin. If anyone would like to share tips, advice on how to get started, or useful documentation etc.

It is probably too late but you can see How to become a Samsung mobile UI Themes Designer blog and Apply on The Themes Overview page.

You have 6 days to prepare and submit your application and then the Window closes for 2 years.
