+The built-in client `wac` reads from the standard input, and sends the lines as
+messages to the specified recipient in the argument. The received messages are
+shown in the standard output. The phone should be specified in the following
+format:
 
-Received and sent text messages are displayed with the name of the sender:
+	<country code><phone>@s.whatsapp.net
 
-	<me>: Have you ever seen a supernova?
-	Neil: Well...
-	Neil: Sometimes I power my phone screen in the dark
-	Neil: At maximum brightness
+For example, the number 666666666 in Spain, would be
+`34666666666@s.whatsapp.net`. Some examples using the standard input:
 
+	% PHONE=34666666666@s.whatsapp.net
+	% wac $PHONE
+	Hi, do you read me?
+	Yes!
+
+It can also be piped, as any UNIX like program, for example:
+
+	% echo Hi from the command line | wac $PHONE
+
+Or to get a remote shell:
+
+	% mkfifo fifo
+	% wac < fifo | bash > fifo
