Welcome to BackendPro
to start to develop using it.
I won't go into a lot here but my best advise to start off with is just have a play with the system before you think about writing code using it. Of course if you want the full documentation on BackendPro just get it here.
My only real advice is be very carefull with member accounts and access control permissions untill you understand them fully. Performing certain actions could lock you out of your system.
So head over to the login page and get started. Currently you are logged out.
