Reply to Recording/ripping vinyl

I'm on a pretty hefty budget after purchasing my turntables and a few records so I need to make sure if I have this right before I go out and buy. I googled the easiest way to get this done, and if I have it right all I would need is an rca cable leading from my mixer (from line out) to my laptop's headphone jack and some recording software. Just thought I'd confirm whether or not this is correct.
