      environment there is <a href="/news/2016/10/06/jekyll-3-3-is-here/#3-siteurl-is-set-by-the-development-server">an
      exception</a>, if you are running <code>jekyll serve</code> in a development environment

      key in the <a href="/docs/front-matter/">front matter</a>. NOTE: This variable is not applicable to
      posts and documents in user-defined collections. Use the <code>categories</code> variable to get similar
