 This is a very quick initial note about installing Shairport Sync on FreeBSD. Some manual installation is required.
 
-The build instructions here install back ends for `sndio` (native to OpenBSD) and ALSA. ALSA is, or course, the Advanced Linux Sound Architecture, so it is not "native" to FreeBSD. It has, however, been ported to some architectures (not to the ARM, unfortunately), so it should work pretty well on those.
