如何通过单击没有任何代码隐藏的按钮将列表框中的项目添加到列表中？

I am new to MVVM, and also fairly new to WPF. As a matter of fact I started programming just a few months ago. MVVM is really dng my head in with the binding concept, and I have been trying for days now to just simply make an application that allows you to select an item from a listbx, and when you click on the add button the selected item should be saved in a new list. The second listbox displays the latest items added, and you can select an item and delete it by using another button. ususally I would go for the click event and decorate my codebehind with pretty little methods, but I really want to learn how to do all this by using bindings and no codebehind. I would be extremly happy for any help, and please remember that I am new to this and I really want to keep it as simple as possible :) with kind regards DanielaI am new to MVVM, and also fairly new to WPF.
