Ok so place it on the root. Then bootstrap recovery and then reboot recovery. Once in cm use the volume rockers as scroll buttons the power button as the back button and the camera button as the enter button. Scroll down to backup /restore and choose to make a backup. After the backup finishes reboot the phone. Then reboot recovery again and scroll down to mounts and storage and mount system and data (when they're mounted it will say unmount data or unmount system and data may already be mounted) then go down to installed zip from SD card and then choose zip from SD card and find squids rom and install it.
