 # NQPTP – Not Quite PTP
-`nqptp` is a daemon that monitors timing data from any [PTP](https://en.wikipedia.org/wiki/Precision_Time_Protocol) clocks – up to 64 – it sees on ports 319 and 320. It maintains records for each clock, identified by Clock ID and IP.
+`nqptp` is a daemon that monitors timing data from [PTP](https://en.wikipedia.org/wiki/Precision_Time_Protocol) clocks it sees on ports 319 and 320. It maintains records for one clock, identified by its Clock ID.
 
 It is a companion application to [Shairport Sync](https://github.com/mikebrady/shairport-sync) and provides timing information for AirPlay 2 operation.

 ## Notes
 The `nqptp` application requires exclusive access to ports 319 and 320.
 This means that it can not coexist with any other user of those ports, such as full PTP service daemons.
-In Linux, `nqptp` runs as a low-priviliged user but is given special access to ports 319 and 320 during installation.
