Clean Install of SSD in a MacBook Pro Mid 2112

I'm getting more confused the more I read. I know this is easy, but can someone give me a line by line instructions to install a Crucial MX 300 525 GB SSD in this machine? The easiest most reliable way to do this. I want a clean install of El Capitan or Sierra. I'm using El Capitan right now and I have the install app copied to a thumb drive. And does Sierra run or load any faster than El Capitan? I want to keep the current HDD for a backup. Appreciate any help, sorry to rehash.

Mid 2112 MacBook Pro, Intel I7 2.9 GHz, 16 GB DDR3, 750 GB HDD, No Full HD, Intel Graphics 4000

MacBook, Mac OS X (10.6.8)

My apologies, I think I understand you now:

The best way to clean install:

Create a bootable USB using create install media or DiskMaker (Install El Cap will need to be in your Applications folder, or on an attached drive)

Once successful, open System Prefs>Startup Disk

If you see the USB drive, you were successful

Shut down your Mac

Install the SSD

Boot your Mac while holding Option

Boot of the USB drive

Make sure your SSD is Mac OS Extended formatted in Disk Utility

Install El Cap on the SSD

When this completes and your Mac restarts, go through the setup procedure

Personally when I clean install, I transfer my applications by connecting the old drive, in your case, via an adaptor

If you don't transfer anything, make a new account and boot into the OS

Reinstall applications and transfer data as needed from the old drive
