+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.

+But git may eventually be unable to tell the first bad commit among

You can even skip a range of commits, instead of just one commit,
using the "'<commit1>'..'<commit2>'" notation. For example:
or bad, you can bisect by issuing the command:
------------
-$ git bisect run my_script
+$ git bisect run my_script arguments

Note that the script (`my_script` in the above example) should
$ git bisect run make # "make" builds the app

outside the repository to prevent interactions between the bisect,
make and test processes and the scripts.

+Does the same as the previous example, but on a single line.
