+After a bisect session, to clean up the bisection state and return to
+the original HEAD, issue the following command:
 
 ------------------------------------------------
 $ git bisect reset
 ------------------------------------------------
 
-This resets the tree to the original branch instead of being on the
-bisection commit ("git bisect start" will also do that, as it resets
-the bisection state).
+By default, this will return your tree to the commit that was checked
+out before `git bisect start`.  (A new `git bisect start` will also do
+that, as it cleans up the old bisection state.)
+
+With an optional argument, you can return to a different commit
+instead:
+
+------------------------------------------------
+$ git bisect reset <commit>
+------------------------------------------------
+
+For example, `git bisect reset HEAD` will leave you on the current
+bisection commit and avoid switching commits at all, while `git bisect
+reset bisect/bad` will check out the first bad revision.
