     version: 0.0
     os: linux
     files:
       - source: /MyApp.zip
         destination: /var/www/myapp
     hooks:
       BeforeInstall:
         - location: scripts/install_dependencies.sh
         - location: scripts/setup_environment.sh
       AfterInstall:
         - location: scripts/start_application.sh
     

5. Start a Deployment:
