Make sure the handles spin freely on the rope so they don't get twisted.
Start slowly and once you get the rhythm & timing you can then speed up to skip as a fast clip.
Keep knees slightly bent and push off the balls of you feet. (Don't use a knee movement to kick your feet out behind you)You just need to clear the rope so don't bounce up high. Can land on both feet or alternate left then right.
Once you have that you can introduce stuff like; as the rope clears your feet and begins coming up your back, cross your arms so your hands are outside the oppersite elbow for cross overs or every now and then put in a higher bounce and spin the rope twice per jump. Move about, forward and back, left and right etc and play with foot movements to put variety into it.
Have been told that 3mins skipping ='s 9min jogging and yes it is good for your coordination, rythem and timing. Great exercise so have fun with it.
