I Maximilian, how are you doing?
Please don't let your frustration block you from moving forward.
This new pair of eyes from new developers, especially for Windows and Mac is very valuable to us all. Especially in what concerns improving our documentation/website new devevlopers onboarding page and experience.
Linux tends to be favoured in our website only to the fact that it is the OS of choice of your core developers. No further distinction of OS is done based in any other factor. It is just matter of what is mainly used by them. That's all.
Your contributions would be much appreciated!
