-This hook is invoked by linkgit:git-send-email[1]. It takes a single parameter,

+This hook is invoked by linkgit:git-send-email[1].
+
+It takes these command line arguments. They are,
+1. the name of the file which holds the contents of the email to be sent.
+2. The name of the file which holds the SMTP envelope and headers of the email.
+
+The SMTP envelope and headers are passed in the exact same way as they
+are passed to the user's Mail Transport Agent (MTA). In effect, the email
+given to the user's MTA, is the contents of $2 followed by the contents
+of $1.
+
+Below is an example for a few common headers. Take notice of the
+capitalization and multi-line tab structure.

To allow further flexibility in the Git hook, the SMTP header information of the email which git-send-email intends to send, is now passed as the 2nd argument to the sendemail-validate hook. As an example, this can be useful for acting upon keywords in the subject or specific email addresses.
