What is the issue/what feature do you want to develop?

• VBAixGUI lacks a basic documentation of the usage within a VB.NET Application Project

What is the current application?

• GUI Development

What are the requirements?

• Some basic MWE's are still missing, see #46

How do we want to solve it?

Did you add a documentation @PhOstmann , can we close the issue?
