Crank brothers cleats come well packaged, with clear instructions and everything you might need including shims as an option.
The crank brothers mechanism is different from SPD I'm not sure if I like it yet. It may not be a good choice for a novice rider. There is no adjusting release pressure. In my opinion a novice does better with a very easy release. Easy release does not mean accidental release as long as your technique is good.
Crank brothers pedals such as the mallet are great blend of flat and clipless, but it may be better to just commit to one or the other.
