@@ -14,7 +14,12 @@ If you have sw.grp from the full version of the game, you may also want
 to install jfsw_hires_pack for some graphic enhancements (don't bother
 trying if all you have is the shareware sw.grp: it segfaults on startup).
 
-Note #1: If you run into an issue turning left or right with the mouse,
+Optional dependencies: SDL2 and/or fluidsynth. These will be autodetected
+and used if they are installed. SDL2 provides a slightly better user
+experience (YMMV), but fluidsynth doesn't actually seem to *do* anything
+for jfsw.
+
+Note: If you run into an issue turning left or right with the mouse,
 edit the config file (~/.jfsw/sw.cfg) and change MouseAnalogAxes0 to
 "analog_turning" and MouseAnalogAxes1 to "analog_moving". The digital
 axes should have "" values.
