+# User guide
+
+This short guide explains how to use directly the Ansible playbook to install OSM to an OpenStack infrastructure.
+
+## Prerequisites
+The ansible playbook requires `ansible` and `openstacksdk` to be executed. `python-openstackclient` is not mandatory but highly recommended. They are part of Python pip and can be installed as follows:
+
+`$ sudo -H pip install python-openstackclient "openstacksdk<1" "ansible>=2.9,<3"`
+
+## Execute the playbook
+
+In order to execute the playbook, it is required an OpenStack openrc file. It can be downloaded from the OpenStack web interface Horizon.
+
+After that, it can be loaded with the following command:
+
+`$ . openrc`
+
+Then, all the credentials are loaded in the bash environment. Now it is possible to execute the playbook to configure OpenStack and install OSM:
+
+`$ ansible-playbook -e external_network_name=<your openstack external network> site.yml`
