+# If you don't want to store sensitive information, like your database password,
+# in your source code, provide the password or a full connection URL as an
+# environment variable when you boot the app. For example:
+#
+#   DATABASE_PASSWORD="some-password"
+#
+# or
+#
+#   DATABASE_URL="mysql2://myuser:mypass@localhost/somedatabase"
+#
+# If the connection URL is provided in the special DATABASE_URL environment
+# variable, Rails will automatically merge its configuration values on top of
+# the values provided in this file. Alternatively, you can specify a connection
+# URL environment variable explicitly:
+#
+#   production:
+#     url: <%= ENV["MY_APP_DATABASE_URL"] %>
+#
+# You can specify password environment variable in a similar way:
+#   
+#   production:
+#     password: <%= ENV["DATABASE_PASSWORD"] %>
+#
+# Read https://guides.rubyonrails.org/configuring.html#configuring-a-database
+# for a full overview on how database connection configuration can be specified.
