+Note that as e-mail is the system of reference for code reviews, and some
+people prefer it over a web interface, we do not generate automated mail
+when a review changes state, for example by clicking "Accept Revision" in
+the web interface. Thus, please type LGTM into the comment box to accept
+a change from Phabricator.
+
+Committing a change
+-------------------
+
+Arcanist can manage the commit transparently. It will retrieve the description,
+reviewers, the ``Differential Revision``, etc from the review and commit it to the repository.
+
+::
+
+ arc patch D<Revision>
+ arc commit --revision D<Revision>
+
+
+When committing an LLVM change that has been reviewed using
+Phabricator, the convention is for the commit message to end with the
+line:
+
+::
+
+ Differential Revision: <URL>
+
+where ``<URL>`` is the URL for the code review, starting with
+``http://reviews.llvm.org/``.
+
+Note that Arcanist will add this automatically.
+
+This allows people reading the version history to see the review for
+context. This also allows Phabricator to detect the commit, close the
+review, and add a link from the review to the commit.
