"Help/Tutorial" page in WPF menu bar - wpf

Question

I've added a menu bar to application, because I wanted to add there a little tutorial under "Help" menu. Like Help - > "How to use the program", that's the idea.
I would like this to be, a pop up window that has ability to include text, as well as photos to better explain the program. It should be able to have a little bit of formatting (just a simple spaces, tabulator, new lines) so the text with photos looks clean.
To sum up, I need an idea, a tutorial, a guide, an adivce - you name it what should I use to implement those things, because right now I am in a blank spot.
#edit Hope this clarifies my question.

To do this you need menu items:
<Window x:Class="WPFTestApp2.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Grid>
<Menu>
<MenuItem Header="Help">
<MenuItem Header="How to use this program" Click="MenuItem_Click"></MenuItem>
</MenuItem>
</Menu>
</Grid>
</Window>
And you would need a click handler:
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
namespace WPFTestApp2
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
private void MenuItem_Click(object sender, RoutedEventArgs e)
{
HelpWindow window = new HelpWindow();
window.Show();
}
}
}
Then, you would need to create a new window with all the help text you would like. You would need to design that window and I think that is really dependent on what the application does.
