.env.dist

+# In all environments, the following files are loaded if they exist,
+# the latter taking precedence over the former:
+#
+#  * .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
+#
+# Real environment variables win over .env files.
+#
+# DO NOT DEFINE PRODUCTION SECRETS IN THIS FILE NOR IN ANY OTHER COMMITTED FILES.
+#
+# Run "composer dump-env prod" to compile .env files for production use (requires symfony/flex >=1.2).
