There really isn't any "step by step" procedure ... just open the low point drains and allow any RV antifreeze to gravity drain, run the pump if you want to help the process. Fill the fresh water tank with water, make sure any water heater bypass valves are set correctly, and use the pump to pressurize and purge the system of air. Some also choose to sanitize the water system at this time by adding a bit of bleach (1/4 to 1/2 cup) to the fresh water tank and running it through using the pump but you'd probably want to do a second flush with fresh water to minimize any bleach after small. That's about it, not much more to than that.
