This guide will explain how to setup the editor for Divinity: Original Sin.

Now you are ready to start creating mods with The Divinity Engine :) Check the next editor guide for how to get started with mods.
Open the Galaxy Client and click the "more" button (next to the play button) for the game. Then choose "other" from the menu and click "The Divinity Engine" - done!
