+This is also useful as a library for downloading a Tor Browser Bundle. This API
+isn't really stable, more "stabilizing." Feel free to use it, but it may still
+change a little.
+
+To create a new instance, use:
+
+``` Go
+client, err = tbserve.NewClient(*verbose, *lang, *system, *arch, &content)
+```
+
+Customize the client using the exposed variables and methods:
+
+``` Go
+client.Host = *host
+client.Port = *port
+client.TBS.Profile = &content
+client.TBS.PassThroughArgs = flag.Args()
+```
+
+And serve the controller:
+
+``` Go
+if err := client.Serve(); err != nil {
+  log.Fatal(err)
+}
+```
