- Create the following folder structure in your root project directory: .ebextensions/supervisor

- Place the supervisor.config under .ebextensions/

- Place the setup.sh under .ebextensions/supervisor/

- Run "chmod +x .ebextensions/supervisor/setup.sh"

- Place the supervisord.conf under .ebextensions/supervisor/

- Place the supervisor_laravel.conf under .ebextensions/supervisor/

Feel free to update the files according to your needs. 
You mostly will need to change the command inside the supervisor_laravel.conf file

If you want to check if the supervisor is running, connect to the instance and run "supervisorctl status".
If you want stop/kill supervisor run "ps aux | grep "[/]usr/bin/supervisord", get the PID and then run "kill PID_NUMBER"
