It takes you to this page:
https://staging-openms.readthedocs.io/en/staging/docs/tutorials/TOPP/topp-and-openms-introduction.html

As you can see, it describes TOPP, TOPPView and OpenMS.

I would like to see this page clearly state that there are two ways of accessing TOPP tools: either using a graphical interface like TOPPView or KNIME for workflows, or you can use the command line.
