-Two programs are provided for system monitoring in the *hardstatus* line of **GNU
-Screen**: a CPU usage monitor and a memory usage monitor.  These programs are
-intended to use minimal system resources.
+A simple, lightweight program provided for system monitoring in the *status*
+line of **tmux**.
 
-The CPU usage monitor outputs a percent CPU usage over all processors that is
-updated every second.  It also displays a textual bar graph of the current
-percent usage where every '|' character represents 10% usage.  
+The memory monitor displays the used and available memory.
 
-The memory monitor is updated every three seconds and displays the used and
-available memory.
+The CPU usage monitor outputs a percent CPU usage over all processors. It also

-Example::
+The system load average is also displayed.
 
-  Mem:2885MB/7987MB  Cpu:[|||||     ]  51.2%

-Configuring GNU Screen_
+Configuring tmux_
 =======================
 
 
-The ``$HOME/.screenrc`` file must be edited to make use of the installed
-programs, ``screen-cpu-usage`` and ``screen-mem-usage``.
-
-An example configuration::
-
-  # backticks to display information in the statusbar
-  backtick 1 0 0 /usr/local/bin/screen-mem-usage
-  backtick 2 0 0 /usr/local/bin/screen-cpu-usage
-
-  hardstatus alwayslastline  
-  hardstatus string '%{kg}Host:%{kG}%H%{kg} %=%{kb}Mem:%{kB}%1`  %{ky}Cpu:%{kY}%2`%%  %{kR}Load:%{kr}%l%=%{kc} %D %m/%d %{kC}%C%a%{w}' 
-
-The example configuration will result in::
-
-  Host:flea   Mem:2961MB/7987MB  Cpu:[||        ]  25.6%  Load:0.64 0.35 0.28 Fri 09/11 12:56am
+Edit ``$HOME/.tmux.conf`` to display the programs output in *status-left* or
+*status-right*.  For example::
 
+  set -g status-interval 2
+  set -g status-left "#S #[fg=green,bg=black,bright]#(tmux-mem-cpu-load 2)#[default]" 
 
+Note that the first argument to `tmux-mem-cpu-load` should be the same number
+of seconds that *status-interval* is set at.
