+This directory contains the Tatu (SSH-as-a-Service) DevStack plugin.
+
+To configure Tatu with DevStack, you will need to enable this plugin and
+the Tatu service by adding one line to the [[local|localrc]] section of
+your local.conf file.
+
+To enable the plugin, add a line of the form:
+
+    enable_plugin tatu <GITURL> [GITREF]
+
+where
+
+    <GITURL> is the URL of a Tatu repository
+    [GITREF] is an optional git ref (branch/ref/tag).  The default is master.
+
+For example
+
+    enable_plugin tatu https://github.com/pinodeca/tatu stable/queens
+
+For more information, see the "Externally Hosted Plugins" section of
+https://docs.openstack.org/devstack/latest/plugins.html
