Installing the cylinders is the same thing as installing new suspension shocks, its a direct replacement. When thats installed, you have to mount your tank and compressor somewhere, install the pressure switch, and run the compressor on a solinoid. Once thats finished, figure out where you want to mount your valves, on the tank, and exit valves maybe underneath the car somewhere. From there you need to wire each valve to your controller, run the line from the battery to connect to the controller and compressor. Then install all your fittings, on the cylinders, valves, and tank. Once thats complete, turn on the compressor, and check for any leaks if there is any, and from there, you have yourself a decent suspension.
