Similar idea to godot 4.0, but taken in a completely different direction.
It contains all of my currently in use engine modules. See the [changelog](https://github.com/Relintai/pandemonium_engine/blob/master/CHANGELOG.md) for a more comprehensive list of changes.
I don't have anything (like an official webpage) set up at the moment, but temporarily you can download binaries from the github actions tab [[here]](https://github.com/Relintai/pandemonium_engine), or the releases tab [[here]](https://github.com/Relintai/pandemonium_engine/releases).
Some of the documentation is available in this repo under the doc/engine folder. [[Here]](https://github.com/Relintai/pandemonium_engine/tree/master/doc/engine).
You can also look at the official 3.x Godot documentation, it will work mostly (sometimes with trivial modifications). It is hosted on [ReadTheDocs](https://docs.godotengine.org), and is maintained by the Godot community in its own [GitHub repository](https://github.com/godotengine/godot-docs).
It's also worth looking at official godot 3.x resources, like this [awesome Godot list](https://github.com/godotengine/awesome-godot), and there are also a number of other [godot learning resources](https://docs.godotengine.org/en/latest/community/tutorials.html)
