In case you already have a unlocked bootloader, please take a minute to go over the cautionary notes before you proceed:

Warning!

You run a chance of voiding your phones warranty when you flash custom stuff, make note.

Download the latest build, rename it to recovery.img. It is imperative that you rename it to nothing else but recovery.img. Place the renamed file in the platform-tools folder of ADB you’ve setup. If you haven’t setup ADB then do it now.

Turn off your phone and boot into fastboot mode: hold volume UP & power together until you see the display say fastboot mode.

Navigate to the platform-tools folder inside ADB and issue the following:

One the process completes, disconnect your phone from the computer and hold the power button to turn it off. To enter the custom recovery hold down the volume DOWN & power buttons.

You should now be greeted by the TWRP custom recovery screen.
