How Do I Use This Crossover Cable?

[sthief09]

I looked on google but didn't find anything helpful.

I accidentally bought a crossover cable instead of a regular network cable one day at staples because I was in a rush and they were closing. when I realized what it was for I decided to keep it and use it. but I can't figure out how the damn thing works. I was hoping I could hook it up to both computers and send files but I guess not. that would've been cool.
