+# Silkaj: new CLI Duniter client
+
+I am pleased to announce a new Duniter client!
+It's a client from CLI (command line interface) written with Python 3.
+
+- [Diaspora\* post](https://framasphere.org/posts/2226277)
+- [Code repository](https://github.com/duniter/silkaj) with a tutorial to install it.
+
+This client was started almost two weeks ago and needed to be mature enough before public release.
