In the previous example, you saw how to create and apply patches. You can, of course, attach these patch files directly to an email, but Git provides a way to send patches directly as emails with the git send-email command. The command requires some setting up, but how you do that is heavily dependent on your general mail and SMTP configuration. A general guide can be found in the Git help pages or by visiting: http://git-scm.com/docs/git-send-email.
