1) Computer
2) Steam "Big Picture"
3) Xbox wired controller

Okay, so first things first you need to open the "Big Picture" mode (you can do this by clicking the controller icon at the top right or pressing the center Xbox icon on your controller). Once there go to the "Library" tab and go to Counter-Strike Global Offensive and start the game.

So you've made it this far, now we'll get into the actual configuration of the controller.

At this point you'll need to go to Options > Controller
Now you'll be at the button set up (you'll have to set this up various times in game).
Here you use the d'pad to select the buttons you want to change.

Finally we're almost done!
Now you need to start a game (preferably bots so you can get used to the controller). For this example I used the "No Bots" mode.

The last thing you need to do is the command "Bind <key> "joystick 1"". The quotation marks around joystick 1 are required for this to work properly so it knows its a phrase, because as the command implies it enables the joysticks on your controller so you can look and move, the reason you'd bind this command is for easy access to the command with a touch of a key. (you need to press this key when you join a new server not map)

Oh and dont forget to reset the buttons to how you want them! :)

Thanks for reading!
I hope this helps some people out there having troble setting their controller up.

P.S. there is a handy button for a 180 spin!
