 * SPIFFS: You will need to add SPIFFS file upload support to Arduino if you want to upload files to the ESP12F, see: https://github.com/esp8266/arduino-esp8266fs-plugin
 
 
+### Uploading Data to SPIFFS
+The website served on the ESP8266 lives in the 'data' folder inside the sketchyour sketch. To upload this data you need the 'Arduino ESP8266 filesystem uploader' plugin. Find it [here](https://github.com/esp8266/arduino-esp8266fs-plugin).
+You will find the tool/function in Arduino > Tools > ESP8266 Sketch Data Upload (make sure the directory path is correct). Close the Serial Monitor prior to uploading data.

 ### Uploading Code
 For ESP12F use the following settings in Arduino IDE
