+# Role `distribution_check`
+
+This role checks if the distribution of the hosts is supported (part of the provided distribution support spec.) and fails if it's not.
+
+If a hosts distribution and either an accompanying distribution version, major version or release is supported, the role doesn't fail for the host in question.
+
+## Required Arguments
+
+For the required arguments look at the [`argument_specs.yaml`](./meta/argument_specs.yaml).
+
+## `hosts`
+
+The `hosts` for this role need to be the machines for which you want to make sure their distribution is supported.
