+### Server options
+
+The XMage server locates by default the configuration file from the current working directory to the relative path `config/config.xml`
+(`config\config.xml` in Windows). To change this location, start the server with the property `xmage.config.path` set
+to the desired location, for example `-Dxmage.config.path=config/otherconfig.xml`. The option can be set from the 
+XMageLauncher in `Settings > Java > Server java options`.
