Update: Nexus 7 (2012) link has been added. Get to flashing!
Update 2: And the Nexus 10 is now good to go.
The Android 4.4 update has started rolling out to the Nexus 7 and Nexus 10 tablets around the world. But if your tablet has yet to receive the update, then don't despair — we've got a quick walkthrough that'll get you updated in a few minutes, assuming you've got a little experience with a command line.
Note that this is for stock Nexus tablets, and for people who want to update without really doing any real hackery, but don't mind a little command line work. Nothing we do here is permanent, other than the update itself. If you've already flashed a custom recovery, you should be able to update manually using that, instead of our method. And with that...
