+# Self-hosting
+This plugin launches a temporary built-in web listener that stores the 
+validation response in memory. It can share port 80 with IIS and 
+other (Microsoft) software so this doesn't interfere with regular traffic. 
+Not all software supports this port sharing feature though. If you get errors 
+telling you that the listener cannot be started, please look for another
+validation method.
