+If you have input that results in a crash or an erroneous output, then
+that is a bug. We try respond to bug-reports promptly, and fix them as
+soon as possible. Help us by sending a defective input file, so we can
+reproduce the problem. Make it small, so we can easily debug the
+problem. Don't forget to tell which version of LilyPond you use! Send
+the report to @email{bug-lilypond@@gnu.org}.
+
+When you've found a bug, have a look at our
+@uref{http://lilypond.org/doc/v2.3/bugs/,bug database} to see if it
+has already been reported. You could also try doing a few searches
+on the mailing list for the bug. Sometimes the bug will have already
+been reported and a fix or workaround is already known.
+
+Here is an example of a good bug report:
+
+@verbatim
+
+It seems that placement of accidentals is broken. In the
+following example, the accidental touches the note head.
+
+Using Mac OSX 10.3.5, fink package lilypond-unstable
+
+\version "2.3.16"
+\relative c''{
+ a4 b cis d
+}
+@end verbatim
+
+@lilypond
+\version "2.3.16"
+\relative c''{
+ \override Accidental #'extra-offset = #'(1.0 . 0)
+ a4 b cis d
+}
+@end lilypond
