L702X Yosemite DSDT/SSDT patching question to experts?

Hello, so I followed this http://www.insanelymac.com/forum/topic/293246-osx-on-dell-vostro-3450-inspiron-n4110-xps-l702x-uefi-clover/page-1 guide and successfully installed Yosemite on L702X laptop. Now everything is working fine. Except Display port. I read the forums and found the answer that I need to patch the DSDT file from this https://github.com/RehabMan/Laptop-DSDT-Patch repo the pach name is "HD3000 High Resolution" in order to make Display port work. So my quostion is can anyone guide me how to do that? Cuz im pretty new in hackintoshing.
