# In all environments, the following files are loaded if they exist,

# * .env contains default values for the environment variables needed by the app
# * .env.local uncommitted file with local overrides
# * .env.$APP_ENV committed environment-specific defaults
# * .env.$APP_ENV.local uncommitted environment-specific overrides
