 ## Presentation ##
 
-* Deploy `user.js` script on a drone to fly it
+* Deploy `user.js` flight script on a drone swarm
 
-* Compile all required libraries to run flight scripts
+* Compile all required libraries to run the flight script
 
 ## Parameters ##
 
-* autopilot-ip: IPv4 address to identify the autpilot from the companion board
+* autopilot-ip: IPv4 address to identify the autopilot from the companion board
 
-* id: User chosen ID for the drone (must be unique in a swarm, will be used as an identifier in multicast communications)
+* drone-guid-list: List of computer id on which flight script must be deployed
 
 * is-a-simulation: Must be set to 'true' to automatically take off during simulation
 
-* multicast-ipv6: IPv6 of the multicast group of the swarm
+* multicast-ip: IPv6 of the multicast group of the swarm
 
 * net-if: Network interface used for multicast traffic
 
-* drone-id-list: List of the drone IDs of the swarm (recommended to add the current drone ID)
+* flight-script: URL of user's script to execute to fly drone swarm
 
-* flight-script: User script to execute to fly drone swarm
+* subscriber-guid-list: List of computer id on which subscription script must be deployed
 
 ## How it works ##
 
-Run `quickjs binary location` `scripts location`/main.js `scripts location`/user.js
+For each computer listed in `drone-guid-list` and `subscriber-guid-list` a drone SR will be instanciated.
+Each instance will return a `instance-path`. Under this path one will find `quickjs binary` in `bin` folder
+and `scripts` in `etc` folder.
+Run `quickjs binary location` `scripts location`/main.js `scripts location`/user.js .
