Like the thread says, you need Android SDK installed on your computer and some knowledge of ADB.
Here's a good start on how to set up SDK and ADB
Beginner's Guide to Installing the SDK and ADB (Updated 3/5/11).
You can pretty much disregard the part about using visionary or Z4, that's for the Froyo root method. Once you get that set up, you'll be ready to navigate to your ADB folder and enter the commands that are posted. I mentioned in my original post that I'm not writing a how to, mainly because I'm already fully rooted and have never done this. But if you have any questions feel free to ask, either here (I'll do the best I can to help) or in the original thread... folks here and over a XDA are generally nice and are willing to help new users, so don't be afraid to ask questions
Just a side note - The key to any rooting is to read, read, read.. get yourself familiarized with the rooting process and what's involved.
