+@findex timeclock-when-to-leave
+  Use the @kbd{M-x timeclock-in} command when you start working on a
+project, and @kbd{M-x timeclock-out} command when you're done.  Once
+you've collected some data, you can use @kbd{M-x
+timeclock-workday-remaining} to see how much time is left to work today
+(assuming a typical average of 8 hours a day), and @kbd{M-x

+@findex timeclock-modeline-display
+  If you want Emacs to display the amount of time ``left'' of your
+workday in the mode line, either customize the
+@code{timeclock-modeline-display} variable and set its value to
+@code{t}, or invoke the @kbd{M-x timeclock-modeline-display} command.

+@vindex timeclock-ask-before-exiting
+  Ending the current Emacs session might or might not mean that you stop
+working on the project.  If you'd like Emacs to ask you about this, set
+the value of the variable @code{timeclock-ask-before-exiting} to
+@code{t} (via @kbd{M-x customize}).  By default, only an explicit
+@kbd{M-x timeclock-out} tells Emacs you stopped working on a project.
+
+@cindex @file{.timelog} file
+@vindex timeclock-file
+@findex timeclock-reread-log
+  The timeclock functions work by accumulating the data on a file called
+@file{.timelog} in the user's home directory.  (On MS-DOS, this file is
+called @file{_timelog}, since leading dots in file names are not
+allowed.)  The name of this file can be changed by customizing the
+variable @code{timeclock-file}.  If you edit this file manually, or if
+you change the value of any of timeclock's customizable variables, you
+should run the command @kbd{M-x timeclock-reread-log}.  This will
+recompute any discrepancies in your average working time, and will make
+sure that the various display functions return the correct value.
