+cdist-type__jool(7)
+===================
+
+NAME
+----
+cdist-type__jool - Configures a NAT64 instance using jool.
+
+
+DESCRIPTION
+-----------
+This type configures an instance of a NAT64 using jool. This type **does not**
+configure anything related to the other capacities of the jool project, such as
+SIIT (see the `jool_siit` daemon / `__jool_siit` type - unimplemented at this
+time). See https://jool.mx
+
+Note that this type is only implemented for the Alpine Linux operating system.
+
+Note that this type currently does not implement running several parallel
+instances of jool NAT64. Please contribute your implementation if you do so.
+
+
+REQUIRED PARAMETERS
+-------------------
+None.
+
+
+OPTIONAL PARAMETERS
+-------------------
+instance
+    The instance name, `default` if unspecified.
+
+framework
+    The used translation framework, `netfilter` if unspecified.
+
+pool6
+    The IPv6 prefix used to map IPv4 addresses, `64:ff9b::/96` if unspecified.
+
+
+EXAMPLES
+--------
+
+.. code-block:: sh
+
+    __jool # Everything default
+
+    # or, if you're feeling contrary
+
+    __jool --instance "prettysoup" \
+        --framework "iptables" \
+        --pool6 "2001:DB8:dead:beef::/96"
