 The `make install` installs a `systemd` startup script. You should enable it and start it in the normal way. Note that `nqptp` must run in `root` mode to be able to access ports 319 and 320.
 
 # Notes
-If you wish to use the shared mutex to ensure records are not altered while you are accessing them, you should open your side of the shared memory interface with read-write permission. Be aware that while your program has the mutex lock, it is in a "critical region" wherer it can halt `nqptp`, so keep any activity while you have the lock very short and very simple, e.g. copying it to local memory.
