To install, know that you need a CM13 custom ROM installed on your device, or any other ROM which supports CM13 theme engine. There are some devices that come with Cyanogen OS pre-loaded, and for such devices, there is no need to hunt for CM13 ROM. Installing CM13 isn’t a straightforward thing as it needs lots of preparation: TWRP recovery and/or root and/or bootloader unlock, etc.
