  <title>Add <gui>Help</gui> to the application menu</title>

  <links type="series" style="floatend">
    <title>Set up help</title>
  </links>

  <p>Most GNOME applications should have an application menu. The
  <gui style="menuitem">Help</gui> menu item should go above the
  <gui style="menuitem">About</gui> menu item.</p>

  <example>
  <note>
    <p>This example, based on
    <app href="https://git.gnome.org/browse/cheese/tree/src/cheese-main.vala">Cheese</app>,
    assumes that your application is written in Vala. It will be slightly
    different for other programming languages.</p>
  </note>

  <p>Add the <gui style="menuitem">Help</gui> item to the list of actions:</p>
  <code>
   private const GLib.ActionEntry action_entries[] = {
        <input>{ "help", on_help },</input>
        { "about", on_about },
        { "quit", on_quit }
    };

   add_action_entries (action_entries, my_Gtk_Application);
</code>

  <p>Add the <gui style="menuitem">Help</gui> menu item to the application
  menu:</p>

<code>
  var menu = new GLib.Menu ();
  var section = new GLib.Menu ();

  <input>var item = new GLib.MenuItem (_("_Help"), "app.help");
  item.set_attribute ("accel", "s", "F1");
  section.append_item (item);</input>
</code>

  <p>View the help with <app>Yelp</app> when the
  <gui style="menuitem">Help</gui> menu item is clicked:</p>

<code>
  private void on_help ()
  {
    var screen = main_window.get_screen ();
    try
    {
      Gtk.show_uri (screen, <input>"help:cheese"</input>, Gtk.get_current_event_time ());
    }
    catch (Error err)
    {
      message ("Error opening help: %s", err.message);
    }
  }
</code>

  <p>To link to a section on the <file>index.page</file>, use
  <code>"help:<input>applicationname</input>/index#<input>sectionid</input>"</code>.</p>

  </example>
</page>
