This means that users willing to experience a nearly stock variation of Android, but with a host of added features and customization option, are now enabled to do so. However, it is quite important to say that the nightly builds are usually quite buggy and not stable enough to be used as daily drivers at such an early stage in their development. Various issues might occur with each nightly build; often, fixing one issue creates another one. It usually takes some time before an all-around stable build becomes available.
You can download the nightly builds for both of these Nexus phones by heading to Cyanogen's website (we've provided links right below). Have in mind that you'll find them listed with their codenames - "angler" for the Nexus 6P and "bullhead" for the Nexus 5X. Of course, in order to flash them, you will need to have a custom recovery installed on your handset.
