+# Over-The-Air (OTA) Update

+Grab the firmware from the
+
+ *  [Releases page](https://github.com/jomjol/AI-on-the-edge-device/releases) (Stable, tested versions), or the
+ *  [Automatically build development branch](https://github.com/jomjol/AI-on-the-edge-device/actions?query=branch%3Arolling) (experimental, untested versions). Please have a look on [](https://github.com/jomjol/AI-on-the-edge-device/wiki/Install-a-rolling-%28unstable%29-release) first!
+
+You need:
+* firmware.bin
+* html.zip
+
+### **General remark:** 
+
+- It is always recommended to upload both files, as they are coupled to each other
+- If you make a major update, it might be needed to modify the `config.ini` as it's syntax or context has changed
+- It is recommended to make a **backup** of the `/config`  directory, minimum of the `config.ini`.
+
+
+
+### Access to the update page:
+
+The graphical OTA update can be accessed in the menue "System":
