Don't bother with Goo right now. It's been messed up for quite some time. Download the Flashify application and the TWRP img from Techerrata then use Flashify to flash the recovery image.

Techerrata Downloads - Downloading openrecovery-twrp-2.6.3.4-hammerhead.img
As Rx said, you could also use fastboot commands to flash the recovery img.
fastboot flash recovery recovery.img
In this case, you would rename the file to recovery.img

Thanks, I am kinda new to TWRP, how do I update it?
Just like in the text you quote. Download the file linked, hook up your phone to a pc, reboot phone into bootloader, open a command prompt on the pc and type the above command - either change recovery.img to the twrp filename or rename the file.
The above assumes you have the right drivers installed on your pc.
Always best to know all this as fastboot commands can get you out of a lot of problems.

If you're already rooted you can Install this app and flash it, just go to the TWRP site and download it there.
