 .SYNOPSIS
 	Checks the ping latency 
 .DESCRIPTION
-	This PowerShell script checks the ping latency from the local computer to 10 popular hosts.
+	This PowerShell script measures the ping roundtrip times from the local computer to 10 Internet servers.
 .PARAMETER hosts
 	Specifies the hosts to check, seperated by commata (default is: amazon.com,bing.com,cnn.com,dropbox.com,facebook.com,github.com,google.com,live.com,twitter.com,youtube.com)
 .EXAMPLE
 	PS> ./check-ping
-	✅ Ping latency is 13ms...109ms with 29ms average (0 loss)
+	✅ Ping latency is 29ms average (13ms...109ms, 0 loss)
