+Hello World
+===========
+
+Here is a "Hello, World!" web application written using Wapp:
+
+>
+    #!/usr/bin/tclsh
+    package require wapp
+    proc wapp-default {} {
+      wapp-subst {<h1>Hello, World!</h1>\n}
+    }
+    wapp-start $argv
+
+To run this application using the built-in web-server, store the code above
+in a file (here we use the name "hello.tcl") and do:
+
+>
+    tclsh hello.tcl
+
+To run the app using the built-in web-server bound to all TCP addresses
+and listening on port 8080, use:
+
+>
+    tclsh hello.tcl --server 8080
+
+To run the app as an SCGI server listening on port 9001:
+
+>
+    tclsh hello.tcl --scgi 9001
+
+To run the application as CGI, make the hello.tcl file executable and
+move it into the appropriate directory of the web server.
