How can I make my first Splash Screen at beginning - before anything ?

Hello …I just need to make the First screen of the Game ; in this case will be like some kind of Splash Screen ,
where I can put some information like : the name of company , name of Game , etc.
And another question : how can I test it ? .
thanks so much.

Have a splash scene, and make it scene 0 in the build settings. Then load your next scene after a delay.

thank you for your answer - this is the only things I have on the Project:

Project Tab :
Materials (Folder)
splash1 - ( this a Shader)
splash1 ( this is a texture )
SplashScreen ( this is a Default Asset - with the Unity logo at the left

Thats all - the splash1 at top is a Cube - but cannot see it on the Scene or Game windows.

and when I run the Build is nothing there , just an empty Blue screen.

File > Save Scene

Now you will have a scene in your Project View.
