 On power up, ESP32 will remain awake for calibration purposes (see below) until user presses the __Start__ button on the web page.
 The ESP32 will then periodically wakeup to collect data and send this to the remote host, then return to deep sleep.
 
+## Installation
+
+Download github files into the Arduino IDE sketch folder, removing `-main` from the application folder name.
+
+Compile with PSRAM enabled and the following Partition scheme:
+* ESP32-S3 - `8M with spiffs (...)`
+* ESP32 - `Minimal SPIFFS (...)`
+
+On first installation, the application will start in wifi AP mode - connect to SSID: **ESP32_SG_...**, to allow router and password details to be entered via the web page on `192.168.4.1`. The configuration data file (except passwords) is automatically created, and the application web pages automatically downloaded from GitHub to the SD card **/data** folder when an internet connection is available.
+
+Subsequent updates to the application, or to the **/data** folder files, can be made using the **OTA Upload** tab. The **/data** folder can also be reloaded from GitHub using the **Reload /data** button on the **Edit Config** tab, or by using a WebDAV client.
+
 ## Setup and Calibration
 
 The ESP32 and GY-521 modules fit snugly into a 33mm width x 120mm height PETling:
