+-i|--info::
+       Use the 'info' program to display the manual page, instead of
+       the 'man' program that is used by default.
+
+-m|--man::
+       Use the 'man' program to display the manual page. This may be
+       used to override a value set in the 'help.format'

+
+-w|--web::
+       Use a web browser to display the HTML manual page, instead of
+       the 'man' program that is used by default.

+The web browser can be specified using the configuration variable
+'help.browser', or 'web.browser' if the former is not set. If none of
+these config variables is set, the 'git-web--browse' helper script
+(called by 'git-help') will pick a suitable default. See
+linkgit:git-web--browse[1] for more information about this.
+
+CONFIGURATION VARIABLES
+-----------------------
+
+If no command line option is passed, the 'help.format' configuration
+variable will be checked. The following values are supported for this
+variable; they make 'git-help' behave as their corresponding command
+line option:
+
+* "man" corresponds to '-m|--man',
+* "info" corresponds to '-i|--info',
+* "web" or "html" correspond to '-w|--web',
+
+The 'help.browser', 'web.browser' and 'browser.<tool>.path' will also
+be checked if the 'web' format is chosen (either by command line
+option or configuration variable). See '-w|--web' in the OPTIONS
+section above and linkgit:git-web--browse[1].
+
+Note that these configuration variables should probably be set using
+the '--global' flag, for example like this:
+
+------------------------------------------------
+$ git config --global help.format web
+$ git config --global web.browser firefox
+------------------------------------------------
+
+as they are probably more user specific than repository specific.
+See linkgit:git-config[1] for more information about this.
