+Cover letter
+If you want to present the whole patch set in a separate mail, add
++--cover-letter+ to the +git format-patch+ command (see +man
+git-format-patch+ for further information). This will generate a
+template for an introduction e-mail to your patch series.
+A 'cover letter' may be useful to introduce the changes you propose
+in the following cases:
+* large number of commits in the series;
+* deep impact of the changes in the rest of the project;
+* RFC footnote:[RFC: (Request for comments) change proposal];
+* whenever you feel it will help presenting your work, your choices,
+ the review process, etc.
+Patch revision changelog
+When improvements are requested, the new revision of each commit
+should include a changelog of the modifications between each
+submission. Note that when your patch series is introduced by a cover
+letter, the changelog may be added in the cover letter rather than in
+the individual commits.
+When added to the individual commits, this changelog is added when
+editing the commit message. Below the +Signed-off-by+ section, add
++---+ and your changelog.
+Although the changelog will be visible for the reviewers in the mail
+thread, as well as in http://patchwork.buildroot.org[patchwork], +git+
+will automatically ignores lines below +---+ when the patch will be
+merged. This is the intended behavior: the changelog is not meant to
+be preserved forever in the +git+ history of the project.
+Hereafter the recommended layout:
+Patch title less than 80-character length
+Some more paragraph giving some more details.
+And yet another paragraph giving more details.

+Changes v2 -> v3:
+ - foo bar (suggested by Jane)
+ - bar buz
+Changes v1 -> v2:
+ - alpha bravo (suggested by John)
+ - charly delta
+Any patch revision should include the version number. The version number
+is simply composed of the letter +v+ followed by an +integer+ greater or
+equal to two (i.e. "PATCH v2", "PATCH v3" ...).
+This can be easily handled with +git format-patch+ by using the option
+$ git format-patch --subject-prefix "PATCH v4" \
