+==========================
+Dead man's switch (client)
+==========================
+
+This module is the client part of `dead_mans_switch_server`. It is responsible
+of sending the server status updates, which in turn takes action if those
+updates don't come in time.
+
+Configuration
+=============
+
+After installing this module, you need to fill in the system parameter
+``dead_mans_switch_client.url``. This must be the full URL to the server's
+controller, usually of the form ``https://your.server/dead_mans_switch/alive``.
+
+This module attempts to send CPU and RAM statistics to the server. While this
+is not mandatory, it's helpful for assessing a server's health. If you want
+this, you need to install ``psutil``.
+
+You can also have the number of currently online users logged, but this only
+works if the ``bus`` module is installed and longpolling configured correctly.
+
+Usage
+=====
+
+This module doesn't have any visible effect on the client.
