+====== Programming the Hardware ======
+====== Arduino Libraries ======
+===== Dependencies =====
+It is vital that you have the correct libraries installed in your Arduino to allow it to compile the code.
+You should have

+  * ESP32  esp32 by Espresif System (I have version 1.01)
+  * Ftp support ESP8266FtpServer.h https://github.com/me-no-dev/arduino-esp32fs-plugin/releases/latest \\

+===== Programming using OTA =====
+The nodes can be updated using OTA (Over the Air) wireless programming.\
+To do this you must know the node IP addres. Then, in Arduino, in "tools": port", select the node you wish to update.\\
+Then proceed with Sketch:upload as you would if the node was connected physically.\\
+=== Known Limitation ===
+I have noticed that the Node may need to be powered down and then re-powered after an OTA upload. \\
+Because the MQTT find broker code blocks all other operations, the Node should be successfully connected to a MQTT broker before the update can be undertaken. Also note that, depending on what #defines you have used, after updating, you may still need to physically connect to the node to set SSID and Passwords etc. - But the update should not affect the saved values, so in general, if the code worked before you updated, it should do so again afterwards.
