How to remove and install the digitizer?

I have been doing research on how to remove the digitizer from the nexus 7. Although i haven't yielded any results. I had read through some threads, to find that i should by the lcd/digitizer combo to avoid the hassle. But i don't have the money to buy the combo, only the digitizer. So my question is, how do you remove and install the digitizer from the nexus 7 without breaking the lcd or any other components. Some users have said that they've done this succesfully, so if someone could put together a tutorial on how to do it, that would be awesome!
