Hello, I'm playing this game for a very long time now and I have so many ideas and motivation to experiment. I want to start with server developement. It isn't planned to open a commercial server in future for sure. I want to experiment only on my local machine and want to see if this could be a hobby for me or not. Here are so many things and I simply don't know where to start. I already found the thread which software I need but that's not very helpful as a first step. Also I couldn't find a guideline which first steps I have to do. I think I need some server files. Which ones are good to go with? And how do I install them local? Any tips or tutorials I didn't found yet? I can find out things by myself a bit, here are a lot of tutorials and people who are glad to help with questions. But its a bit hard if I don't even know where to start. So I appreciate any help or tips.
