Fill the expansion tank. There are 2 small hoses that will direct coolant to the right areas to start filling the system. Once it is "full" turn the key to position 2 and the electric pump at the bottom of the tank will pump coolant into the engine. Top off the overflow tank and run the engine for a while. continue to top off as air comes out and finds its way to the expansion tank.
