+        This credentials provider loads the details of pre-provisioned
+        accounts from a YAML file, in the format specified by
+        `etc/accounts.yaml.sample`. It locks accounts while in use, using the
+        external locking mechanism, allowing for multiple python processes
+        to share a single account file, and thus running tests in parallel.
+
+        The accounts_lock_dir must be generated using `lockutils.get_lock_path`
+        from the oslo.concurrency library. For instance:
+
+            accounts_lock_dir = os.path.join(lockutils.get_lock_path(CONF),
+                                             'test_accounts')
+
+        Role names for object storage are optional as long as the
+        `operator` and `reseller_admin` credential types are not used in the
+        accounts file.
+
+        :param identity_version: identity version of the credentials
+        :param admin_role: name of the admin role
+        :param test_accounts_file: path to the accounts YAML file
+        :param accounts_lock_dir: the directory for external locking
+        :param name: name of the hash file (optional)
