+## Setup instructions
+
+### Download jar file
+Download the jar file of the program and put it in a folder, e.g. under  _/home/pi/RhasspyVisualConversationTool_
+
+### Make sure java is installed 
+_which java_ should return something. If it doesn't install a java runtime environment, e.g. with  _apt install openjdk-11-jre_
+
+### Configuration file
+
+Create  _RhasspyVisualConversationTool-settings.ini_ with the following content:
+
+``` 
+language=de-DE
+sslDebug=false
+keystoreFilename=
+keystorePassword=changeme
+
+logFolderPath=/var/log/rhasspyVisualConversationTool
+logLevel=5
+
+mqttClientServerHostname=mqtt.yourServer.com
+mqttClientServerPort=1883
+mqttClientUseSsl=false
+mqttClientUseAuthentication=false
+mqttClientUsername=
+mqttClientPassword=
+
+siteId=
+```
+
+If you have set  _mqttClientUseSsl=true_ it's at least likely you have your own PKI. In that case create a java keystore and put your root certificate in it. Then save the keystore in the folder of the jar and config file and put its filename for  _keystoreFilename_ .
+
+### Create start script
+
+I suggest to use this path:  _/home/pi/Desktop/startConversationTool.sh_
+
+Put this content into the file (adapt the folder if you changed it above):
+
+```
+#!/bin/bash
+
+while(true)
+do
+        cd /home/pi/RhasspyVisualConversationTool/
+
+        /usr/bin/java -jar /home/pi/RhasspyVisualConversationTool/RhasspyVisualConversationTool.jar
+
+        sleep 5
+done
+```
+
+Make it runnable:  _chmod 775 /home/pi/Desktop/startConversationTool.sh_
+
+### Make the script autostart with the graphical user interface
+
+Create this file:  _/home/pi/.config/autostart/conversationTool.desktop_
+
+with the following content:
+
+```
+[Desktop Entry]
+Type=Application
+Exec=/home/pi/Desktop/startConversationTool.sh
+```
+
+### Test run
+When double-clicking your start script the app should come up and connect successfully.
+
+Restart your Raspberry Pi to make sure the script comes up automatically.
