+
+Dynamic inventory for Online resources
+--------------------------------------
+
+Ansible has a dynamic inventory plugin that can list your resources.
+
+1. Create a YAML configuration such as ``online_inventory.yml`` with this content:
+
+.. code-block:: yaml
+
+    plugin: online
+
+2. Set your ``ONLINE_TOKEN`` environment variable with your token.
+    You need to open an account and log into it before you can get a token.
+    You can find your token at the following page: `https://console.online.net/en/api/access <https://console.online.net/en/api/access>_`
+
+3. You can test that your inventory is working by running: ``ansible-inventory -v -i online_inventory.yml --list``
+
+4. Now you can run your playbook or any other module with this inventory:
+
+::
+
+    $ ansible all -i online_inventory.yml -m ping
+    sd-96735 | SUCCESS => {
+        "changed": false,
+        "ping": "pong"
+    }
