+## Node.js realtime server
+
+To run the server, you need to install the dependencies and run the server.
+Please ensure you have followed the OS-specific instructions in doc/ to
+install NodeJS. Once you have node, then you can proceed to install the
+node packages for the realtime server:
+
+    cd realtime
+    npm install #creates node_modules directory
+    node realtime-server.js
+
+That's it!
+
+To run the server as a daemon that will be re-run if it crashes, you can
+use the forever node package.
+
+    sudo npm install -g forever
+    forever start realtime-server.js
