   - The Discover tab allows you to inspect different interesting elements in the project and read small explanations.
-- Once the editor is ready, take a look at the menu bar : several menus are added compared to an empty Unity project. The **"Load levels" menu** offers you 2 options :
-  - The **Day, Sunset, and Night buttons** are shortcut that will load the main scene plus one of the different lighting scenes used in the project but not the gameplay elements
-  - The **Loader** button allows you to load our bootstrap scene. When this scene is loaded you can enter **Play mode** and experience the demo as in a built executable.
