+short_description: Manages volumes on the cloudscale.ch IaaS service
+description:
+  - Create, attach/detach and delete volumes on the cloudscale.ch IaaS service.
+  - All operations are performed using the cloudscale.ch public API v1.
+  - "For details consult the full API documentation:
+     U(https://www.cloudscale.ch/en/api/v1)."
+  - A valid API token is required for all operations. You can create as many
+    tokens as you like using the cloudscale.ch control panel at
+    U(https://control.cloudscale.ch).
+notes:
+  - Instead of the I(api_token) parameter the C(CLOUDSCALE_API_TOKEN) environment
+    variable can be used.
+  - To create a new volume at least the I(name) and I(size_gb) options
+    are required.
+  - A volume can be created and attached to a server in the same task.
+version_added: 2.8
