how to setup this module, i download the zip thing and what i do with it?
README.md/#mobile-app-quick-setup. In short, you need to run the editor downloaded from here, and run your project in it. Then your running project should be displayed in the Godot Remote app on your smartphone.
I apologize for such a delay in responding. itch.io doesn’t send me notifications for some reason :(
If you want your own build, then I have a little guide: BUILDING.md. In general, you can build Godot as usual, but with an additional module. Or download it here in the “Download” section.
