You need to be running a custom recovery mod, such as ClockWork Mod. The stock recovery mode will not let you install unofficial packages.

It's unfortunately very late, so I don't really have the time to look up all of the details for you, but you need to use fastboot.exe to flash a custom recovery image. This is assuming you've already unlocked the bootloader (via "fastboot OEM unlock"). If the bootloader is unlocked, there will be a little padlock at the bottom of the screen when turning on the phone.

TL;DR: You need to install a ClockWork Mod recovery image. Make sure it's the right image for your model.
