+-u::
+       Update only files that git already knows about. This is similar
+       to what "git commit -a" does in preparation for making a commit,
+       except that the update is limited to paths specified on the
+       command line. If no paths are specified, all tracked files are
+       updated.
+
 \--::
        This option can be used to separate command-line options from
        the list of files, (useful when filenames might be mistaken
        for command-line options).
 
 
+Configuration
+-------------
+
+The optional configuration variable 'core.excludesfile' indicates a path to a
+file containing patterns of file names to exclude from git-add, similar to
+$GIT_DIR/info/exclude.  Patterns in the exclude file are used in addition to
+those in info/exclude.  See link:repository-layout.html[repository layout].
