 | view | Opens the report viewer. When providing a result zip file from a previous JPlag run - either in a way a source directory would be given or through the `-r` flag. If no file is given the landing page will be opened. |
 | run | Runs JPlag without opening the report viewer. |
 
+When no value is given for the mode flag JPlag tries to guess the best mode. When calling it with submission files, it executes the `run_and_view` mode. When the positional argument is a zip file including a report, it starts the `view` mode and opens the given report. When no arguments are given, the report viewer is started in `view` mode without any given file, leading to the [landing page](###landing-page)

 ### Landing Page
 On the landing page a report can be opened by either dragging the zip file onto the page. Alternatively when clicking the red square a file chooser will open.
