This plugin lets you create fields (metadata) that will be formatted in the same way the main file content is formatted.
For example, in a reStructuredText document, you can define fields containing a value in reStructuredText, and it will be translated to HTML.
To select which fields are translated, list them in the FORMATTED_FIELDS setting in your Pelican configuration file:
FORMATTED_FIELDS = ['read_more', 'some_facts']
