Need otg on nexus 4...please help

Hey guys i have a nexus 4 and need otg for it. Can some one give me a step by step tutorial on how to do it. 
The ones on other forums are a bit to complicated for me...i dont quite get them.

Here is a link from XDA. Seems you need to flash a kernel. If you are rooted that's as easy as getting the .zip and rebooting and flashing.

Edit: I am more than willing to help if you need it! :)
