 A choice inside a wildcard can also be a list or a dictionary of one element containing a list. These are considered anonymous wildcards. With a list it will be an anonymous wildcard with no choice options, and with a dictionary the key will be the options for the choice containing the anonymous wildcard and the value the choices of the anonymous wildcard. Anonymous wildcards can help formatting complex choice values that are used in only one place and thus creating a regular wildcard is not necessary. See test.yaml for examples.
 
+Note: the files should have UTF-8 encoding. The extension will also try with windows-1252 if that fails.

+Wildcard definitions are reloaded automatically on each generation if they change.

 ### Detection of remaining wildcards
 
 This extension should run after any other wildcard extensions, so if you don't use the internal wildcards processing, any remaining wildcards present in the prompt or negative_prompt at this point must be invalid. Usually you might not notice this problem until you check the image metadata, so this option gives you some ways to detect and treat the problem.
