How to cryonics?

And please forgive me if this is a RTFM kind of thing.

I've been reading LW for a time, so I've been frequently exposed to the idea of cryonics. I usually push it to the back of my mind: I'm extremely pessimistic about the odds of being revived, and I'm still young, after all. But I realize this is probably me avoiding a terrible subject rather than an honest attempt to decide. So I've decided to at least figure out what getting frozen would entail.

Is there a practical primer on such an issue? For example; I'm only now entering grad school, and obviously couldn't afford the full cost. But being at a very low risk of death, I feel that I should be able to leverage a low-cost insurance policy into covering such a scenario.
