+==========================
+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 currently online users logged, but this only works if
+the `im_chat` module is installed.
+
+Usage
+=====
+
+This module doesn't have any visible effect on the client.

+==========================
+Dead man's switch (server)
+==========================
+
+This module receives status messages by `dead_mans_switch_client` and notifies
+you if a client instance didn't check back in time.
+
+As a side effect, you'll also get some statistical data from your client
+instances.
+
+Usage
+=====
+
+Install `dead_mans_switch_client` on a customer instance and configure it as
+described in that module's documentation. The clients will register themselves
+with the server automatically. They will show up with their database uuid,
+you'll have to assign a human readable description yourself.
+
+At this point, you can assign a customer to this client instance for reporting
+purposes, and, more important, add followers to the instance. They will be
+notified in case the instance doesn't check back in time. Notification are only
+turned on for instances in state 'active', instances in states 'new' or
+'suspended' will be ignored.
+
+You'll find the instances' current state at Reporting/Customer instances.

+
+* https://www.odoo.com/forum/help-1
+
+Security considerations
+=======================
+
+As the controller receiving status updates is unauthenticated, any internet user
+can have your server create monitoring instance records. While this is annoying,
+it's quite harmless and basically the same as misuse of the fetchmail module.
+
+For a more substantial annoyance, the attacker would have to guess one of your
+client's database uuids, so they functionally are your passwords.
+
+To be sure, consider blocking this controller from unknown origins in your SSL
+proxy. In nginx, it would look like this::
+
+    location /dead_mans_switch/alive {
+    allow   192.168.1.0/24;
+    # add other client's IPs
+    deny    all;
+    }
+
+Known issues / Roadmap
+======================
+
+* matching is done via the database's uuid, so take care to change this if you
+  clone a database
+* logging some postgres stats and disk usage would be nice too
