+#### Can I run several instances of CTB Recorder
+It is possible to define the configuration directory and configuration file, which is used by ctbrec. This way you
+can create several instances with different configurations.
+On Windows, create a file called `ctbrec.l4j.ini` right next to `ctbrec.exe`. Add one of the following settings
+or both to the file:
+
+To change the config directory:
+
+`-Dctbrec.config.dir=C:\Users\boobface\Desktop\ctbrec\conf`
+
+To change only the config file:
+
+`-Dctbrec.config=abc.json`
+
+On Linux and macOS edit `ctbrec.sh` and add one or both of the above mentioned settings to the start line (preferably directly after $JAVA):
+
+`$JAVA -Dctbrec.config=alternate-settings.json -Djdk.gtk.version=3 -cp ctbrec-1.19.1-final.jar ctbrec.ui.Launcher`
