+gridwm
+------
+
+gridwm is an automatic X11 window manager which arranges all windows in a grid.
+
+
+Requirements
+------------
+In order to build gridwm you need the Xlib header files.
+
+
+Installation
+------------
+Edit config.mk to match your local setup. gridwm is installed into
+the /usr/local namespace by default.
+
+Afterwards enter the following command to build and install gridwm (if
+necessary as root):
+
+ make clean install
+
+
+Running gridwm
+--------------
+Add the following line to your .xinitrc to start gridwm using startx:
+
+ exec gridwm
+
+In order to connect gridwm to a specific display, make sure that
+the DISPLAY environment variable is set correctly, e.g.:
+
+ DISPLAY=foo.bar:1 exec wmii
+
+This will start gridwm on display :1 of the host foo.bar.
+
+
+Configuration
+-------------
+The configuration of gridwm is done by customizing the config.h
+source file.
