+# Notes
+
+It is required to overwrite NotebookApp.contents_manager_class to avoid a
+immediate redirect to 404 page upon notebook-loading. Currently this is done
+inline in jupyter_notebook_config.py, but should better be moved to a seperate
+python file and imported in the config. However, I was unable to get the include
+paths right with slapos.
+
+A lot of weirdness comes with loading notebooks into the page. de-stringyfied
+JSONs must be further processed because of unlined-strings. See
