hi jimmy and welcome
to shoot RAW you just have to switch your camera setting on to RAW and then use some post processing software
Canons come with DPP software, though i have never used it myself
i prefer to use lightroom/photoshop although the choice of software is down to personal preference and budget
processing your RAW files is not that much different to processing JPG's , if you are doing this already
if you are not, PP will open up a whole new side to your photography
