 The daemon creates a modular status bar by updating the X root window name
 when it receives a request on its named pipe. It takes an ordered list of
 modules as a parameter, and calls a function in each module to compute a

-request. These requests are made by writing to a named pipe that the daemon

+### Reserved Module Names
+
+Module names may not begin with `daem-` or `daem_` because this namespace
+is reserved for requests that the daemon understands natively. The daemon
+implements the following native requests:
+
+- `daem_all`
+    Update all status bar sections.
+- `daem_quit`
+    Quit the daemon.
 
 Commands
 --------
 
-In the `cmd` directory are shell scripts that perform actions that effect
-the status bar and update the status bar, such as changing the backlight or
-volume levels. These commands can be bound to keys, so the action will be
-carried out and the status bar will be updated when the key is pressed.

+Contributing
+------------

+The goal of this project is to learn how to do neat things on Linux and
+with shell scripts. A great way to do that is to just start hacking. So if

+modules and commands, please submit a pull request. Don't by shy!
