+### Participation in the federated blog
+
+The [federated blog](https://ring.muhokama.fun/blog.html) allows you to share
+articles that are unified by the themes of the webring. Each reference to an
+article lives in the [/data/articles](data/articles) directory and if you are
+part of the ring, you can add your articles freely. Imported items are
+referenced in the [ring's Atom feed](https://ring.muhokama.fun/atom.xml).
