-## Before you start
+Pandemonium Engine is a fork of the [Godot Engine](https://godotengine.org/) (specifically the  
+[3.x](https://github.com/godotengine/godot/commits/3.x) branch). With heavy modifications.
 
-The `Tutorials and resources ( doc_community_tutorials )` page lists
-video tutorials contributed by the community. If you prefer video to text,
-those may be worth a look.

-In case you have trouble with one of the tutorials or your project,
-you can find help on the various `Community channels ( doc_community_channels )`,
-especially the Pandemonium Discord community, Q&A, and IRC.
+Even though lots of things have been changed, most tutorials for godot should work with minimal tweaks.
