This MR provides an enhanced README with information about:
- ways of how to integrate the viewer to GitLab pages or your own webserver
- an architecture diagram that explains how the viewer works
- completed the section on how to set up the Viewer from scratch
- expansion of the config section
Does the result of the MR comply to our "definition of done"?
For everyone re-using the viewer for his/her project.
I added a statement to the CHANGELOG.
