 #### --compile
 Enables compilation of the output file.
 
+### Debug
+Due to the way Squish combines multiple scripts into one, sometimes when a squished script raises an error the traceback 
+will be fairly unhelpful, and point to a line in the unreadable squished script. This is where the debug extension comes in!
+
+#### --enable-debug
+This option includes some code into the squished file which will restore the filenames and line numbers in error messages and 
+tracebacks. This option will increase the size of the output by no more than about 6KB, so may be very much worth it when 
+squishing large tricky-to-debug applications and libraries.
+
+**Note:** Minification may interfere with the line number calculation, use --minify-level=debug to enable all features of minify 
+that don't change line numbers, and everything will be fine.

 ## Squishy reference
 
 A squishy file is actually a Lua script which calls some Squish functions. These functions are listed here.
