-Currently there are no options to the package, it just does what it does,
-Possibly later versions might document how to modify the amount of random distortion that is applied.
+Currently there are no options to the package, However there are several parameters that control the offsets
+and grey levels used to generate the variation. Any of the following
+commands may be defined before loading the package to change the defaults shown below.
 
+\begin{verbatim}
+\providecommand\ttgreyone{0.6}
+\providecommand\ttgreytwo{0.3}
+\providecommand\ttrotatebold{12}
+\providecommand\ttdownbold{20000}
+\providecommand\ttrightbold{35000}
+\providecommand\ttdownshifttwo{20000}
+
+\providecommand\ttrotatenormal{8}
+\providecommand\ttrightnormal{20000}
+\providecommand\ttdownnormal{20000}
+\end{verbatim}
+
+The grey levels should be between 0 and 1 and control the maximim
+amount grey level.
+
+The rotate values can be any angle (measured degrees), but setting values more than 20 makes the text more or less unreadable.
+
+The right and down offsets (which are in the font design units) control the
+maximum horizontal and vertical offsets of the overprinted characters
 
 There is random variability in each letter as you can see by repeating
 a letter repeatededly:
