+### Meta Box
+
+The generator for meta boxes will prompt you for a meta box name, a label for an input, which post type(s) the meta box should be enabled for, and where the box should be positioned based on context and priority. The generator only adds a single text input field for demonstration purposes. Different input types and advanced use cases will require developers to implement them. It may be better to use a plugin like [Advanced Custom Fields][advanced-custom-fields] for some situations, especially when a WordPress admin should be able to manage the fields without devloper help.
