+NAME
+----
+gitmodules - defining submodule properties
+
+SYNOPSIS
+--------
+.gitmodules
+
+
+DESCRIPTION
+-----------
+
+The `.gitmodules` file, located in the top-level directory of a
+gitlink:git[7] working tree, is a text file with a layout matching the
+requirements of gitlink:git-config[1].
+
+The file consists of sections named `module`, divided into one subsection
+per submodule. The subsections are named with the logical name of the
+submodule it describes.
+
+Each submodule can contain the following keys.
+
+module.$name.path::
+	Define a path, relative to the top-level directory of the git
+	working tree, where the submodule is expected to be checked out.
+
+module.$name.url::
+	Define a url from where the submodule repository can be cloned.
+
+
+EXAMPLES
+--------
+
+Consider the following .gitmodules file:
+
+	[module 'libfoo']
+		path = include/foo
+		url = git://example1.com/git/libfoo.git
+
+	[module 'libbar']
+		url = git://example2.com/pub/git/libbar.git
+
+
+This defines two submodules, `libfoo` and `libbar`. The former specifies
+both a checkout path and a suggested url, while the latter only specifies
+a url. This file would make gitlink:git-submodule[1] map the path
+`include/foo` to the submodule `libfoo` and the path `libbar` to the
+submodule `libbar`.
