Creating an Entity Relationship Diagram in Trevor is super simple. 

Go to the toolbar on the left-hand side, and click the compass icon. This will take you to the database map. In here, you can edit the relationships between columns & tables to build your database map, or ERD. 

You can share your map via the share link or by screenshot.
