 USAGE
+=====
 
 Just run hdsploader, the program takes care of everything.
+
+FILES
+=====
+
+The firmware binaries are installed on /usr/share/alsa/firmware/hdsploader
+(or /usr/local/share/alsa/firmware/hdsploader, depending to the prefix
+option of configure).  There will be *.conf files, which define the dsp
+image files for each different card type.
