Showing form inside another form in wpf?

Question

I have a main form which has all the controls and i have to create a new form for help window which guides you to use the main form. I did check about the mdi container but it looks a bit odd to see 2 forms inside another form. Is there any other way for embedding my main form inside another form? like docking?
