- Alternatively, the problem might be due to the fact that the file starts
-with exactly 25 spaces. For this reason, you should make sure that you
-inform us of the exact contents of any file that is needed to reproduce the
-bug. What if the problem only occurs when you have typed the @kbd{C-x C-a}
-command previously? This is why we ask you to give the exact sequence of
-characters you typed since starting the Emacs session.
-
- You should not even say ``visit a file'' instead of @kbd{C-x C-f} unless
-you @emph{know} that it makes no difference which visiting command is used.
-Similarly, rather than saying ``if I have three characters on the line,''
-say ``after I type @kbd{@key{RET} A B C @key{RET} C-p},'' if that is
-the way you entered the text.
-
- So please don't guess any explanations when you report a bug. If you
-want to actually @emph{debug} the problem, and report explanations that
-are more than guesses, that is useful---but please include the facts as
-well.

+
+ If possible, try quickly to reproduce the bug by invoking Emacs with
+@command{emacs -Q} (so that Emacs starts with no initial
+customizations; @pxref{Initial Options}), and repeating the steps that
+you took to trigger the bug. If you can reproduce the bug this way,
+that rules out bugs in your personal customizations. Then your bug
+report should begin by stating that you started Emacs with
+@command{emacs -Q}, followed by the exact sequence of steps for
+reproducing the bug. If possible, inform us of the exact contents of
+any file that is needed to reproduce the bug.
+
+ Some bugs are not reproducible from @command{emacs -Q}; some are not
+easily reproducible at all. In that case, you should report what you
+have---but, as before, please stick to the raw facts about what you
+did to trigger the bug the first time.
