Hi Mike,
In general, the source control setup in Studio is fairly straight forward. After opening the project (the source control settings are project specific), if you haven’t already setup the connection details, you can do so via the “Source Control” tab in the Preferences dialog. In there, you should set up the connection just like you would with P4V (i.e. the ports, user, workspace, password and character encoding if any).
Assuming your project is already in Perforce and you have a Perforce workspace setup, that would be all you need. After that you can submit changes from within Studio. Studio automatically checks out file as you make changes and reverts them if no change has been made. If multiple users are working on the project, we highly recommend syncing the project from Studio itself as doing so will allow you to merge and resolve changes.
There isn’t any official guide at the moment but we are working on that. So stay tuned!
