+Ansible Role
+============
+
+Ansible role for the `OpenDaylight SDN controller`_.
+
+Ansible Dependencies
+--------------------
+
+Ansible Galaxy
+^^^^^^^^^^^^^^
+Releases of this role can also be installed available via `Ansible Galaxy`__
+which ships with Ansible.
+To install the latest version of ansible on RedHat based OSs:
+
+::
+
+    $ sudo yum install -y ansible
+
+
+To install the latest version of ansible on Debian based OSs:
+
+::
+
+    $ sudo apt-add-repository ppa:ansible/ansible
+    $ sudo apt-get update
+    $ sudo apt-get install -y ansible
+
+Roles
+^^^^^
+After you install the **ansible-galaxy** tool, point it at the project's
+**requirements.yml** file to install ODL's role.
+
+::
+
+    [~/ansible-opendaylight]$ ansible-galaxy install -r requirements.yml
+
+The OpenDaylight Ansible role doesn't depend on any other Ansible roles.
+
+Role Variables
+--------------
+
+Karaf Features
+^^^^^^^^^^^^^^
+To set extra Karaf features to be installed at OpenDaylight start time, pass
+them in a list to the **extra_features** variable. The extra features you pass
+will typically be driven by the requirements of your use case.
+
+OpenDaylight normally installs a default set of Karaf features at boot. They
+are recommended, so the ODL Ansible role defaults to installing them. This can
+be customized by overriding the **default_features** variable. You shouldn't
+normally need to do so.
+
+REST API Port
+^^^^^^^^^^^^^
+To change the port on which OpenDaylight's northbound listens for REST API
+calls, use the **odl_rest_port** variable.
+Example Use Case:
+In an Openstack deployment, the swift project is already using the port 818
+which is the default for OpenDaylight and would be in conflict. Use the
+**odl_rest_port** variable to change what OpenDaylight uses.
+
+The Ansible role will handle opening this port in FirewallD if it's active.
+
+Install Method
+^^^^^^^^^^^^^^
+
+OpenDaylight can be installed either via an RPM or a .deb depending on the
+operating system.
+For RedHat based OSs, the valid options for **install_method**
+are **rpm_repo** or **rpm_path**.
+For Debian based OSs, **install_method** can accept either **deb_repo** or
+**deb_path**.
+
+Installing OpenDaylight
+-----------------------
+To install OpenDaylight on your system, you can make use of
+**ansible-playbook**.
+
+On RedHat based OSs, you can install OpenDaylight from the RPM repo
+(recommended) using the playbook **examples/all_defaults_playbook.yml** or from
+a local/remote path to an ODL rpm via
+**examples/rpm_path_install_playbook.yml**.
+
+::
+
+    sudo ansible-playbook -i "localhost," -c local examples/<playbook>
+
+On a Debian based OS, you can install OpenDaylight either from a Debian repo
+using the playbook **examples/deb_repo_install_playbook.yml** or from a
+local/remote Deb path using **examples/deb_path_install_playbook.yml**.
+
+::
+
+    sudo ansible-playbook -i "localhost," -c local examples/<playbook>
+
+You can also use ansible-opendaylight using `Vagrant base box examples of
+Ansible ODL deployments`_.
+
+Example Playbook
+----------------
+The simple example playbook below would install and configure OpenDaylight
+using this role.
+
+::
+
+    ---
+    - hosts: example_host
+        sudo: yes
+    roles:
+        - opendaylight
+
+To override default settings, pass variables to the **opendaylight** role.
+
+::
+
+    ---
+    - hosts: all
+      sudo: yes
+      roles:
+        - role: opendaylight
+          extra_features: ['odl-netvirt-openstack']
+
+Results in:
+
+::
+
+    opendaylight-user@root>feature:list | grep odl-netvirt-openstack
+    odl-netvirt-openstack | <odl-release> | x | odl-netvirt-<odl-release> | OpenDaylight :: NetVirt :: OpenStack
+

+Configuration Management
+========================
+
+The Packaging Layer of the packaging and delivery stack provided by upstream
+OpenDaylight installs OpenDaylight via the Packaging Layer and then
+does any additional configuration required by the particular deployment's
+requirements. Examples include setting Karaf features to install at boot,
+remapping OpenDaylight ports, opening OpenDaylight ports in firewalld and
+managing OpenDaylight's systemd service. As additional knobs are required to
+configure deployments, upstream support should be added here.
