+=====================
+Remote Spawner Plugin
+=====================
+
+This plugin makes use of remote `aexpect
+<https://github.com/avocado-framework/aexpect/>`__ sessions (to remote
+hosts or equivalently remote containers behind remote hosts forwarded
+via specific ports) as slots to schedule test runs on.
+
+It mainly draws inspiration and mimics slot and other
+code from the LXC spawner with the exception of extra configurable
+test timeout that is enforced by aexpect as a dependency and fully
+specific to this type of spawner.
+
+To install the Remote Spawner plugin from pip, use::
+
+    $ sudo pip install avocado-framework-plugin-spawner-remote
+
+After it is installed, add a slot (e.g. "board") to your avocado
+config file::
+
+    [spawner.remote]
+    slots = ['board']
+
+Then you need a JSON file of the same name as the slot. Its contents
+are the command line parameters of aexpect's ``remote_login`` function
+of module ``remote``, e.g.::
+
+    {
+       "client": "telnet",
+       "host": "192.168.64.2",
+       "port": "23",
+       "username": "root",
+       "password": "",
+       "prompt": "#"
+    }
+
+Final important detail: the remote site also needs avocado
+installed.
