+  - Alpine Wall (I(awall)) generates a firewall configuration from the enabled policy files
+    and activates the configuration on the system.
+options:
+  name:
+    description:
+      - One or more policy names.
+    type: list
+    elements: str
+  state:
+    description:
+      - Whether the policies should be enabled or disabled.
+    type: str
+    choices: [ disabled, enabled ]
+    default: enabled
+  activate:
+    description:
+      - Activate the new firewall rules.
+      - Can be run with other steps or on its own.
