Fairly standard stuff. Run it at the prescribed RPM for the allotted time, change the oil, go drive it about a bit, change the oil again and enjoy.

You need to do as they say and run the cam in stationary, then take the car out on the road. Don't granny it. Give it plenty of load (but not labouring) while keeping the revs sensible (<4000rpm) for about 500 miles. Then change the oil and you're pretty much good to go.
