 various command line options to customize your experience:
 
-	-r 320x240   (or --res)
+	-r 320x240       (or --res)
 
 Sets the screen resolution.  Unless --opengl is set, the only valid

-	-d 32         (or --bpp)
+	-d 32            (or --bpp)
 
 Sets the color depth.  If you don't set this, the game should
 autodetect an appropriate value.  Valid values are 16, 24, and 32.

 faster as well -- but it also may not work on older cards.

+	-c               (or --scale=mode)
 
 Graphics scaling mode (bilinear, biadapt or biadv). Default is none.
 Try these to get smoother graphics with cost on performance.
 
-	-b           (or --meleescale=mode)
+	-b               (or --meleescale=mode)
 
 Melee scaling mode (nearest or trilinear). Default is trilinear.
 Slower machine owners can set it to nearest to get better performance
 in melee but degraded visual quality.

-	-g           (or --gamma)
+	-g               (or --gamma)
 
 Sets gamma correction. 1.0 causes no change (unless your graphics card
 is originally set to a different value). Higher than 1.0 makes the
 image brighter, lower than 1.0 makes it darker.

+	-T               (or --speechvol)
 
 Set speech volume (0-100). If set to 0, game runs in 'no speech' mode and 
 oscilloscope reacts to the music.

+			   ADD-ONS
+
+Version 0.3 of The Ur-Quan Masters has basic support for add-on packages.
+Though it is not very elaborate yet, you can install some content add-ons.
+
+Inside the directory where the content is installed, in the content/packages/
+directory, there is a directory 'addons/'. In this directory, you can
+create new directories with .zip files to be used in addition to the
+standard content .zip files.
+When you specify the command-line option '--addon <addon>', the .zip files
+inside the directory content/packages/addons/<addon> will be included
+in the game. '--addon' may be specified more than once to enable multiple
+add-ons.
+
+At the time this version of The Ur-Quan masters is released, there aren't
+any official add-ons yet. Keep an eye on http://uqm.sf.net/ for those.
+Our boards, which can be found on this site too, are a good place
+to start looking for unofficial ones.
