how can i enter the serverquery?

Simply download the latest server version from the downloads page and you’ll find a Server Query Documentation in the doc/serverquery folder. It will explain you, how to use the Server Query

I have read that documentation, but I understand very little about it :grinning:

Use Putty or YatQa or other 3rd party tools to access the ServerQuery

In our old forum we have good how to for putty newcomer.
