I have a corrupted hard drive and I have been told by Apple that I need to completely erase the drive and reinstall the OS.

I'm using El Cap right now and I have a Super Duper bootable clone on an external USB drive.
After I completely wipe the drive, how do I restore from a SD clone?
I looked in the instructions and I can't find exactly what I'm looking for.
Thanks,
Paul
