Installing Google Play Services (Gapps) on cyanogenmod 12.1

Hello,
I just flashed Cyanogenmod 12.1 onto my HTC One M8. My cyanogenmod is running Android 5.1. I am trying to install the Google Play Services so that I can have Google Play Store and other Google apps. Am I downloading the correct version of Gapps for my device? http://www.teamandroid.com/gapps/
I downloaded the 12.1 version.
Thank you.
