Hi, I added SSL-Support via ENV-Variables to the kafka-setup-container which I'd like to contribute. I've seen that the Dockerfile would conflict with an open pull request from @early-lamp-41924 where he added configurable topics. How should I proceed? Just create a pull request? (Sorry, I'm totally new to contributing to larger projects)

Hi Günther. First of all, we appreciate your contribution! To answer your question - feel free to raise the PR now. Dexter's changes will likely require a bit more time to simmer because they larger in scope. Worst case, Dexter will have to merge your changes into his prior to submitting his. No big deal!
