+An Alpine-based Python 3.12 Flask web server which allows you to execute iperf, iperf3, dig, nslookup, netcat, ping, and traceroute commands from a web interface.
 
 # Requirements
 
-You must have a running iperf or iperf 3 server running somewhere in order to perform an iperf/iperf3 test to it.
+You must have a running iperf or iperf 3 server running somewhere in order to perform an iperf/iperf3 test to it. You can also find public iperf3 servers at [https://github.com/R0GGER/public-iperf3-servers](https://github.com/R0GGER/public-iperf3-servers). It's highly recommended that you run your own so you can test end to end performance.
 
 Obviously, you need network connectivity between the two hosts for any of the tests and for ping/traceroute; icmp needs to be permitted..
