 NAME
 ----
-git-format-patch - Some git command not yet documented.
+git-format-patch - Prepare patches for e-mail submission
 
 
 SYNOPSIS
 --------
-'git-format-patch' [ --option ] <args>...
+[verse]
+'git-format-patch' [-n | -k] [-o <dir> | --stdout] [--attach] [-s] [-c]
+		 [--diff-options] <his> [<mine>]
 
 DESCRIPTION
 -----------
-Does something not yet documented.
+Prepare each commit with its patch since <mine> head forked from
+<his> head, one file per patch formatted to resemble UNIX mailbox
+format, for e-mail submission or use with gitlink:git-am[1].
+
+Each output file is numbered sequentially from 1, and uses the
+first line of the commit message (massaged for pathname safety)
+as the filename.
+
+When -o is specified, output files are created in <dir>; otherwise
+they are created in the current working directory.  This option
+is ignored if --stdout is specified.
+
+When -n is specified, instead of "[PATCH] Subject", the first
+line is formatted as "[PATCH N/M] Subject", unless you have only
+one patch.
 
 
 OPTIONS
 -------
---option::
-	Some option not yet documented.
+-o|--output-directory <dir>::
+	Use <dir> to store the resulting files, instead of the
+	current working directory.
+
+-n|--numbered::
+	Name output in '[PATCH n/m]' format.
+
+-k|--keep-subject::
+	Do not strip/add '[PATCH]' from the first line of the
+	commit log message.
+
+-s|--signoff::
+	Add `Signed-off-by:` line to the commit message, using
+	the committer identity of yourself.
+
+-c|--check::
+        Display suspicious lines in the patch.  The definition
+        of 'suspicious lines' is currently the lines that has
+        trailing whitespaces, and the lines whose indentation
+        has a SP character immediately followed by a TAB
+        character.
+
+--stdout::
+	This flag generates the mbox formatted output to the
+	standard output, instead of saving them into a file per
+	patch and implies --mbox.
+
+--attach::
+	Create attachments instead of inlining patches.
+
 
-<args>...::
-	Some argument not yet documented.
+CONFIGURATION
+-------------
+You can specify extra mail header lines to be added to each
+message in the repository configuration as follows:
+
+[format]
+        headers = "Organization: git-foo\n"
+
+
+EXAMPLES
+--------
+
+git-format-patch -k --stdout R1..R2 | git-am -3 -k::
+	Extract commits between revisions R1 and R2, and apply
+	them on top of the current branch using `git-am` to
+	cherry-pick them.
+
+git-format-patch origin::
+	Extract commits the current branch accumulated since it
+	pulled from origin the last time in a patch form for
+	e-mail submission.
+
+git-format-patch -M -B origin::
+	The same as the previous one, except detect and handle
+	renames and complete rewrites intelligently to produce
+	renaming patch.  A renaming patch reduces the amount of
+	text output, and generally makes it easier to review
+	it.  Note that the "patch" program does not understand
+	renaming patch well, so use it only when you know the
+	recipient uses git to apply your patch.
