+### Sources
 
     $ git clone https://github.com/Chocobozzz/PeerTube
     $ cd PeerTube
-    # npm install -g electron-prebuilt
     $ npm install

+## Usage

+### Run the server

     $ npm start
 
 ### Test with 3 fresh nodes
 
-    $ bin/clean_test.sh
-    $ bin/run_servers.sh
+    $ npm run clean:server:test
+    $ npm run play
 
 Then you will can access to the three nodes at `http://localhost:900{1,2,3}`. If you call "make friends" on `http://localhost:9002`, the pod 2 and 3 will become friends. Then if you call "make friends" on `http://localhost:9001` it will become friend with the pod 2 and 3 (check the configuration files). Then the pod will communicate with each others. If you add a video on the pod 3 you'll can see it on the pod 1 and 2 :)

 You can test it inside Docker with the [PeerTube-Docker repository](https://github.com/Chocobozzz/PeerTube-Docker). Moreover it can help you to check how to create an environment with the required dependencies for PeerTube on a GNU/Linux distribution.
