A gitlab project at contain submodule and both the project and submodule also contain a readme.md file. The readme.md of the top project is given
Top Readme.md
=============
[Link to folder](folder)
[Link to submodule folder](sub)
[Link to submodule Readme.md](sub/README.md)
The first link work as the brower opens at the subfolder but the other two link does not work, I get a page not found message.
How do you create links to files in a submodule as well as to the submodule as is self?
