A lot of Android 5.1 ROMs have been coming up lately, mostly based on either CyanogenMod 12.1 or AOSP. And as is the case with all AOSP based ROMs, you’ve to install Google services separately from recovery alongside the ROM as a package called Gapps.
Gapps packages consists of Google apps that usually comes pre-installed on all Google certified Android devices. But since these packages are custom made, you get the freedom to choose between a variety of package sizes.
