...The plugin exposes a helper tag to expose the appropriate meta tags to support the automated discovery of your feed. Simply place {% json_feed_meta %} someplace in your template's <head> section, to output the necessary metadata. The plugin uses Jekyll's smartify filter for processing the site title and post titles. This will translate plain ASCII punctuation into "smart" typographic punctuation. This will not render or strip any Markdown you may be using in a title.
