RSS isn't being offered explicitly #14
Description
Hello!
While the index.xml for homepage (contains all the posts) is generated at https://themes.gohugo.io/theme/er/index.xml, the same isn't offered explicitly to the reader. On homepage there is neither the RSS icon nor the menu text like "Subscribe" or "Feed" etc.
Similarly, the index.xml for tag & category page is generated (contains all the posts with that specific tag or category) but isn't offered explicitly to the user. E.g. For tag "markdown" the index.xml is generated at https://themes.gohugo.io//theme/er/tags/markdown/index.xml but is not mentioned on the "markdown" tag page.
