+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-browse-help' script (called by
+'git-help') will pick a suitable default.
++
+You can explicitly provide a full path to your prefered browser by
+setting the configuration variable 'browser.<tool>.path'. For example,
+you can configure the absolute path to firefox by setting
+'browser.firefox.path'. Otherwise, 'git-browse-help' assumes the tool
+is available in PATH.
++
+Note that the script tries, as much as possible, to display the HTML
+page in a new tab on an already opened browser.
