I'm assuming you have stock unrooted firmware? The easiest way is to install philz kernel from stock(3e) recovery, then reboot to recovery and flash a newer recovery that is capable of flashing the newer versions of android. If you just want to install CM12.1 straight away just back up your efs then:
1. Download the DVLSH kernel .zip from HERE
2. Download the philz 6.48.4 from HERE
3. Reboot into stock recovery, flash the DVLSH kernel(if your firmware build is DVL**, you could probably reboot into system no problem)
4. Reboot to recovery(not system), flash the philz 6.48.4
5. Reboot to recovery(not system), follow the steps for installing in the CM12.1 thread after backing up etc
Keep the DVLSH kernel. Once you install CM, you will have CM recovery, which only allows you to flash signed .zips(which this one is)
EDIT - The philz 6.48.4 is also signed and is probably the more useful one to keep, being compatible with the newer roms
