Issues with wp mod to disable system write protection

I'm a total noob to phone development, so when I read guides about installing the wp_mod, I'm confused. It's the last step to rooting this and getting rid of this crapware, so I really want to get it done. I downloaded the file and I copied it to my SD, downloaded terminal emulator to run the su command, but that's where I get lost. Can anyone sort of walk me through it? Thank you.
