+= Using Ansible =
+
+Ansible is a configuration management system that does not require any special installation on the nodes besides Python and SSH. Currently most UFO software can be deployed with it.
+
+== Installing Ansible ==
+
+Ansible has to be installed only on the machine from which the installation should be orchestrated. The simplest way is to setup a virtual env and install Ansible from PyPI:
+
+{{{
+$ mkvirtualenv ansible
+$ (workon ansible)
+$ pip install ansible
+}}}
+
+A machine state is configured through Ansible playbooks and roles. The UFO configuration can be cloned via
+
+{{{
+$ git clone http://ufo.kit.edu/git/playbooks
+}}}
+
+In there you find a `setup.yml` mapping hosts onto roles and giving them tags. Hosts are specified in a hosts file, one example is already present as `hosts.sample`. To run a playbook you have to specifiy the hosts file, the user (in our case root) and optionally which tag to run:
+
+{{{
+$ ansible-playbook -i hosts -u root -t compute setup.yml
+}}}
+
