Introduction to Aerys WebSockets.
# Install dependencies.
composer install
# Run Aerys in debug mode.
# Debug mode ensures we're only using a single worker. Otherwise we might end
# up with two websocket clients connecting to two different workers.
# Later you would replace the current broadcasting with something like Redis, so
# you can have as many workers as you'd like.
