With Unity started, open the project from the previous chapter.

Since we want to keep our projects nice and tidy, we are going to do some refining of our project's structure before starting with this project. Create the following folders:

Place the scene from the previous chapter in your Scenes folder.

Next, move the terrain object and Terrain Assets folder to the Terrains folder, so everything having to do with our terrains is in one place.

Place your tree prefab we made in the Prefabs folder.

Place the scripts from Standard Assets\Character Controllers\Sources\Scripts to your Scripts folder (optionally in a folder called Character).

Move the First Person Controller prefab to the Prefabs folder.

Move the Skyboxes and Water folders to the Materials folder, deleting the Daylight Simple Water prefab...
