to bind to UDP port 5353. This effectively impedes other mDNS
stacks from running on the host. Use this as a security
measure to make sure that only Avahi is responsible for mDNS
- traffic. Please note that we do no recommend running multiple
+ traffic. Please note that we do not recommend running multiple
mDNS stacks on the same host simultaneously. This hampers
reliability and is a waste of resources. However, to not annoy
people this option defaults to "no".</p>
