How to restore a Unity3D game project

I was told that to backup a Unity3D game project I only have to copy the entire project folder to another location or to another storage device.

What is the procedure to restore a backed up Unity 3D project?
Let´s say that my computer crashes and I wish to re-create my game project in a new PC from a backup.

Copy the backup to the desired location and open it with Unity.
