Godot Version

Question

I heard that Godot’s code is open-source. How do I join the open-source community? Do I just log into Github, or do I need to get permission.

I think, with this questions you need read articles about how to deal with OpenSource projects
and they read how to contribute How to contribute — Godot Engine (stable) documentation in English

If you want look into Godot code you even no need to login GitHub - godotengine/godot: Godot Engine – Multi-platform 2D and 3D game engine
