+        This is the first time you the digitizer. You have been automatically routed to the <b>initial setup procedure</b>. 
+        This procedure should adjust the setting to your local counter. Basically you can customize your settings in five steps.
+        <br>
+        In the final step the inital setup will be disabled and it will restart to the normal mode.  
+        <br>
+        <br>
+        Just use the buttons "Next" and "Previous" to nagivate through the process. 
+        <br>
+    </p>
+    <p>
+        Follow the instructions:
+    </p>    
+
+    <p>
+    <ol>
+    <li>Create reference image <br>
+        Basis for the position references and the marking of the digits and counters.</li>
+    <li>Define two unique references <br>
+        Used to align the individual camera shot and identify the absolut positions</li>
+    <li>Define the digits <br>
+        Digital digits to be recognized</li>
+    <li>Define the analog counters <br>
+        Analog counters to be identified</li>
+    <li>General settings <br>
+        Most can stay to the default value - also MQTT connection can be specified here</li>
+    </ol>
+    <p>
+
+After step 5 you switch of the setup mode, reboot and start in normal mode!
