I try to get this into our organization environment as a way of learning. But some categories are not relevant for us. So maybe a way of defining categories to disable could help here.

Solution:

• have a configuraiton file packed into the container in which we can disable certain categories of challenges which is empty by default but shows with tests how to disable certain categories of challenges (e.g. intro and web3?)

Will be solved outside of hacktoberfest as this is a major rewrite of config versus code.
