+module: bigiq_regkey_pool
+short_description: Manages registration key pools on BIG-IQ
+description:
+  - Manages registration key (regkey) pools on a BIG-IQ. These pools function as
+    a container in-which you will add lists of registration keys. To add registration
+    keys, use the C(bigiq_regkey_license) module.
+version_added: "2.5"
+options:
+  name:
+    description:
+      - Specifies the name of the registration key pool.
+      - You must be mindful to name your registration pools unique names. While
+        BIG-IQ does not require this, this module does. If you do not do this,
+        the behavior of the module is undefined and you may end up putting
+        licenses in the wrong registration key pool.
+    required: True
+  description:
+    description:
+      - A description to attach to the pool.
+  state:
+    description:
+      - The state of the regkey pool on the system.
+      - When C(present), guarantees that the pool exists.
+      - When C(absent), removes the pool, and the licenses it contains, from the
+        system.
+    default: present
+    choices:
+      - absent
+      - present
+requirements:
+  - BIG-IQ >= 5.3.0
