Publishing from RSS Guide
Our RSS reader converts some tags from the RSS items to tags for the Jekyll front matter:
<category>: tags, comma separated. Since only 4 tags can be used in a post on DEV, only the first four tags will be used from the RSS item.
Only if the "Mark the RSS source as canonical URL by default" option is enabled in the Publishing from RSS settings.
The article content is prioritized in this order:
<description>. The HTML will be converted to Markdown as the body of the DEV post.
If you're using a Medium RSS feed, Tweet links, YouTube, and Gist iframes are converted to Liquid tags.
