+The supported configuration fields are:
+
+**env**
+  List of environment variables that can be used to set this option.
+  Each entry includes a ``name`` field specifying the environment variable name.
+  The name should be in uppercase and should be prefixed with the collection name.
+  Multiple environment variables can be listed for the same option.
+  The first environment variable in the list takes precedence if multiple are set.
+  This is commonly used for plugins (especially inventory plugins) to allow configuration through environment variables.
+
+
+**ini**
+  List of configuration file settings that can be used to set this option.
+  Each entry includes a ``section`` field for the configuration file section and a ``key`` field for the configuration key. Both should be in lowercase and should be prefixed with the collection name.
+  Multiple configuration settings can be listed for the same option.
+  This allows plugins to be configured via ansible.cfg.
+
+
+**vars**
+  List of Ansible variables that can be used to set this option.
+  Each entry includes a ``name`` field specifying the variable name.
+  The name should be in lowercase and should be prefixed with the collection name.
+  Multiple variables can be listed for the same option.
+  Variables follow Ansible's variable precedence rules.
+  This allows plugins to be configured via Ansible variables.

 To access the configuration settings in your plugin, use ``self.get_option(<option_name>)``. 
 Some plugin types handle this differently:
