VR - Player Start Position?

I need to define the Player Start Position for VR.

I was not able to find a Tutorial / Guide that shows how to do that step by step.
a Video Tutorial would be amazing.

Does anyone know a good source or how to do that?
Thanks a lot!

The playerstart actor has a direction arrow that indicates the forward direction the player is facing. Use the basic transformation tool in the editor to rotate the player.
