Firstly, discord is entirely the wrong medium for documentation.
Secondly, documentation should be at least as accessible as the code. That is to say, if I can view the code without creating an account for some service, then I should also be able to read the documentation too.
I set up a very straightforward Godot dev environment yesterday using toolbox which is built on top of rootless Podman.
The nice thing about toolbox is that it uses my native host Wayland compositor. So whatever I have running in the toolbox can be interacted normally through sway (my host WM).
You can either distribute a container image with your given toolbox configured, or just document the setup steps.
