First of all you need the SteamCMD. You can download it here:
https://steamcdn-a.akamaihd.net/client/installer/steamcmd.zip

Extract the file in a folder.
Now you need to execute this file.

After that, we need to create a folder for the server.

The next thing we gonna do is login:

Now you can start the download with:

If the download was sucessful, you have to type
in the console close the SteamCMD.

Now you can start your server running "Launch_Server.bat", which is located in your
folder.

You can configurate the server, if you open the file "playlists.info" in the folder:

I can not see my server / No one can connect to my server
Please make sure, that you have opened all the required ports in your router. If the everything is set correctly, but the problem still occurs, please contact your internet provider.
Or look for your router model here:
https://portforward.com/router.htm

Is there another way instead of opening the ports?
Yes, you can also host your server through a VPN network like "Hamachi". Of course only the people in the VPN network will be able to join the server then.
If forwarding your ports doesn´t work, please contact your ISP, i won´t be able to help you.

The SteamCMD download failed! What should I do now?
Mostly you just need to retry the download, then the problem should be fixed.

How do I update my server?
Just open the SteamCMD and login again, then retry the Step "Downloading the files" it will be checked which files need to be updated.

To automate these steps to setup/upgrade a server, i created a tool, the group can be founde here:

The tool itself is hosted on Github, which can be found here:
