+SockJS test server
+==================
+
+In order to test sockjs server implementation the server needs to
+provide a standarized sockjs endpoint that will can used by various
+sockjs-related tests. For example by QUnit or
+[Sockjs-protocol](https://github.com/sockjs/sockjs-protocol) tests.
+
+This small code does exactly that - runs a simple server that supports
+the following SockJS services:
+
+ * `/echo`
+ * `/disabled_websocket_echo`
+ * `/cookie_needed_echo`
+ * `/close`
+ * `/ticker`
+ * `/amplify`
+ * `/broadcast`
+
+If you just want to quickly run it:
+
+    npm install
+    node server.js
+
+
+If you want to run do development it's recommended to run `make
+test_server` from the top `sockjs-node` directory:
+
+    cd ../..
+    make test_server
