+If you want to change the syntax highlighting in the block, you can
+change it like this: >
+	:let g:help_example_languages = #{ vim: 'vim', sh: 'bash' }
+The key represents the annotation marker name, and the value is the 'syntax'
+name.  By default, help files support only Vim script highlighting.
+Note: When setting "g:help_example_languages", if you do not include "vim"
+key, the Vim syntax highlighting will not be enabled. If you set it to an
+empty value, syntax highlighting for embedded languages will be disabled.
+
+Further note: including additional syntax languages into help files may not
+always work perfectly, if the included 'syntax' script does not account for
+such an import.
+						*help-notation*
 The following are highlighted differently in a Vim help file:
   - a special key name expressed either in <> notation as in <PageDown>, or
     as a Ctrl character as in CTRL-X
