By default, Hugo will create an unlimited number of RSS entries. You can limit the number of articles included in the built-in RSS templates by assigning a numeric value to rssLimit: field in your project’s config file.
The following values will also be included in the RSS output if specified in your site’s configuration:
languageCode = "en-us"
copyright = "This work is licensed under a Creative Commons Attribution-ShareAlike 4.0 International License."
name = "My Name Here"
