Ah, I didn't realize you wanted the long version. If you follow jcase's instructions from start to finish (including running Use RockMyMoto and MotoWPNoMo) you'll be good to go. First thing you'll need to do is use RSD Lite to downgrade to 4.2.2, from there you can use a bunch of exploits to remove write protection (MotoWPNoMo) and root 4.2.2 (RockMyMoto). Once that's done, you can upgrade to 4.4 and follow jcase's guide (SlapMyMoto) to root your Verizon phone with 4.4.
If you're new to rooting, follow this guide:
