+testserver
+==========
+
+Simple node.js webserver for websocket testing.
+
+The server serves static files in the ../testclient directory.
+There is a websocket server listening at `/echo`, which simply echoes received
+messages.
+
+
+Preconditions
+-------------
+Install node.js v4.x.x or higher (v6.x.x is recommended).
+Install the npm package manager.
+Run `npm install` in the testserver directory.
+
+
+Starting the server
+-------------------
+To start the server use the `npm start` command.
+The server is listening on port 3000 by default.
+The port can be overridden by setting the `port` environment variable.
+
+
+Manual clean up
+---------------
+
+The node_modules subdirectory can be deleted manually.
+No other artifacts are created.
