What experience do you have? Been discussed lots of times if you have a mooch, try the search box  
It's reasonably straightforward, Haynes or workshop manual will walk you through if you're not au fait with the mechanics of it.
Might be worth soaking the hubs/disks with WD40 just in case they're a bit seized onto the hub.

Yes if the disks are rusted they can be a PITA to get off the hub and with ABS you can't just cut them in half.
