Configuring the server
If you want to change the configuration of your server (after the initial setup) you will need to edit some files. They can be edited using any Text Editor program, such as Notepad (pre-installed to all Windows based PC's)
Before editing any configuration files, you should ALWAYS stop your server first.
To navigate to the server's configuration files (and save files) type %appdata% into the Windows search bar, then double-click the "Necesse" folder
The server configuration file is named "server.cfg" and is located at C:\Users\YourPCUsernameHere\AppData\Roaming\Necesse\cfg
The world configuration file is named "worldSettings.cfg" and is located at C:\Users\YourPCUsernameHere\AppData\Roaming\Necesse\saves\YourWorldNamehere.zip
The world is in a Compressed (zipped) .zip folder by default, meaning you will have to extract the files contained inside by right-clicking and selecting "Extract Here" - rename the original YourWorldNameHere.zip to something different.
Then you need to edit the "worldSettings.cfg" file.
Then right-click the YourWorldNameHere folder, and hover over "Send to" and click "Compressed (zipped) folder"
