+yggdrasil
+=========
+
+Deploy yggdrasil using Ansible.
+
+Dependencies
+------------
+
+ansible_lsb needs additional packages on some systems,
+those need to be available
+
+
+Role Variables
+--------------
+
+For available variables take a look at the config template,
+it is currently the only place with variables.
+
+Example Playbook
+----------------
+
+    - hosts: servers
+      roles:
+         - role: yggdrasil
+           become: yes
