 DESCRIPTION
 -----------
-Searches list of files `git-ls-files` produces for lines
-containing a match to the given pattern.
+Look for specified patterns in the working tree files, blobs
+registered in the index file, or given tree objects.
 
 
 OPTIONS
 -------
-<option>...::
-	Either an option to pass to `grep` or `git-ls-files`.
-	Some `grep` options, such as `-C` and `-m`, that take
-	parameters are known to `git-grep`.
+--cached::
+	Instead of searching in the working tree files, check
+	the blobs registerd in the index file.
 
-<pattern>::
-	The pattern to look for.
+-a | --text::
+	Process binary files as if they were text.
 
-<path>...::
+-i | --ignore-case::
+	Ignore case differences between the patterns and the
+	files.
 
-	Optional paths to limit the set of files to be searched;
-	passed to `git-ls-files`.
+-w | --word-regexp::
+	Match the pattern only at word boundary (either begin at the
+	beginning of a line, or preceded by a non-word character; end at
+	the end of a line or followed by a non-word character).
+
+-v | --invert-match::
+	Select non-matching lines.
+
+-E | --extended-regexp | -G | --basic-regexp::
+	Use POSIX extended/basic regexp for patterns.  Default
+	is to use basic regexp.
+
+-n::
+	Prefix the line number to matching lines.
+
+-l | --files-with-matches | -L | --files-without-match::
+	Instead of showing every matched line, show only the
+	names of files that contain (or do not contain) matches.
+
+-c | --count::
+	Instead of showing every matched line, show the number of
+	lines that match.
+
+-[ABC] <context>::
+	Show `context` trailing (`A` -- after), or leading (`B`
+	-- before), or both (`C` -- context) lines, and place a
+	line containing `--` between continguous groups of
+	matches.
+
+-f <file>::
+	Read patterns from <file>, one per line.
+
+`<tree>...`::
+	Search blobs in the trees for specified patterns.
+
+`--`::
+	Signals the end of options; the rest of the parameters
+	are <path> limiters.
