+simple X screensaver
+================================================================================
+
+A simple screensaver inspired by xssstate[1].
+
+
+Dependencies
+--------------------------------------------------------------------------------
+
+- libX11
+- libXScrnSaver
+
+
+Installation
+--------------------------------------------------------------------------------
+
+Configuration is done through 'config.h'. You will need to set the program to be
+run when the screensaver is activated. It doesn't need to be the full path, but
+it must be in your PATH variable if that's the case.
+
+After editing config.h, compile and install.
+
+ $ make
+ $ make install
+
+
+Usage
+--------------------------------------------------------------------------------
+
+sxss doesn't accept any arguments. You can simply add it to your '.xinitrc' (or
+what have you) the following line.
+
+ sxss &
