If CM is already installed, gapps can be side-loaded by going into recovery, selecting adb, then on the pc using
<code>
adb sideload ./gapps-600-base-20151112-1-signed.zip
</code>

Gapps for CM13 can be found here:\\

If storage on the system partition is limited, the pico version might work:\\

CM12.1 and CM13 need a different partition size as gapps packages have become too big.
