I try to override the following template which is under www.example.net/newsletter/manage with my own
I already asked the question Override template and block from a module?, and I understood it. But I struggle to find out, how to override this one.
I added my custom template file
newsletter.phtml to my module:
What step is required next? I guess I need to add a layout file too, but how do I know how it has to be named?
I need a walkthrough for this one please so that I can understand how this all works together.
