 Start up the Tundra server with rendering enabled so that you can see the scene. Here we choose the Physics2 example scene which consists of a large number of physics objects and a ball suspended above them. The server mode is enabled so that clients can connect. Additionally the tundra-addons.json configuration file is loaded, which allows the HttpServerModule (implements the SceneAPI REST service) to be loaded. The SceneAPI REST service is bound to port 2346.
 
 <pre>
-Tundra --config tundra.json --config tundra-addons.json --file scenes/Physics2/scene.txml 
- --server --httpport 2346
+Tundra --config tundra.json --config tundra-addons.json --file scenes/Physics2/scene.txml --server --httpport 2346
 </pre>
 
 Note: if running the server from prebuilt binaries, the --config command line options can be omitted, as the tundra-addons.json configuration file is already being run by default.

 ### JavaScript client library
 
-The Synchronization client code is housed in the WebTundra code base [https://github.com/realxtend/webtundra](https://github.com/realxtend/webtundra), dev2 branch. See its documentation for full details. Some simple examples are described here:
+The Synchronization client code is housed in the WebTundra code base [https://github.com/realxtend/webtundra](https://github.com/realxtend/webtundra). See its documentation for full details. Some simple example is described here:
 
-Initializing the client framework:
+Clone WebTundra from GitHub: `git clone https://github.com/realXtend/WebTundra.git`
 
-(using a packaged build)
+Install [`node.js`](http://nodejs.org/) and [`grunt`](http://gruntjs.com/) for making build:
 
-<pre>
-var client = tundra.createWebTundraClient();
-</pre>
+1. Install [node.js](http://nodejs.org/)
+2. Run `npm install` on the repo root folder to fetch dependencies.
+3. Run `npm install -g grunt-cli` to install the grunt executable as a global tool.
 
-(using development sources)
+Run [`grunt`](http://gruntjs.com/) in WebTundra root folder:
 
-<pre>
-var client = new TundraClient();
-</pre>
+<pre>grunt build</pre>
 
-After creation, the client is also available as TundraSDK.framework.client.
+Run the server with `TundraConsole --server --headless --file scenes/Physics/scene.txml`
 
 Connecting to a server:
 
-<pre>
-TundraSDK.framework.client.connect(address, loginProperties);
-</pre>
-
-where address is the WebSocket protocol specifier + the server address including the port, for example "ws://127.0.0.1:2345" and loginProperties is a JavaScript object containing data to be sent during login, for example
-
-<pre>
-{
-    username : "MyUserName"
-}
-</pre>
-
-Accessing the scene's entities: (a JavaScript array)
-
-<pre>
-var entities = TundraSDK.framework.scene.entities;
-</pre>
-
-Getting a scene entity by id:
-
-<pre>
-var entity = TundraSDK.framework.scene.entityById(id);
-</pre>
+Start apache2 or node.js http-server in `WebTundra/build` folder and open client.html and press connect.
