Anything specific you're having problems with?
To start, just follow the guide. Install Pitool and then connect the headset (USB, DP and power).
It's pretty plug and play.
As a former Rift guy, I was super confused about the HTC base stations. They're devil devices compared to the Rift sensors. There's only a power cable and they make a scary buzzing sound. How the hell do they connect to the computer???
Not to worry though, the HTC base station will be detected automatically. Pretty sure it needs to be set to "A" by pushing the little button on the back of the station, if you're using only one.
Oh, and also install SteamVR, if you haven't already done so.
