What is the Unity Dashabord?

Hi, I’m a newbie to Unity, and I saw this Unity Dashboard. I don’t quite understand what it is. I see there are many services, but I don’t know what are they used for, and why I should use them. And, also, I see a “Create New Project” Button. What is a new project in Unity Dashboard? And, also, what are the services for?
Thanks in advance.

This will help.:slight_smile:
