 Patterns are requested by the app from the ESP8266, so as new patterns are added, they're automatically listed in the app.
 
-The web app is stored in SPIFFS (on-board flash memory).
+The web app is stored in a file system in on-board flash memory.   The file system used is LittleFS *(Note: prior versions used SPIFFS)*.
 
 The web app is a single page app that uses [jQuery](https://jquery.com) and [Bootstrap](http://getbootstrap.com).  It has buttons for On/Off, a slider for brightness, a pattern selector, and a color picker (using [jQuery MiniColors](http://labs.abeautifulsite.net/jquery-minicolors)).  Event handlers for the controls are wired up, so you don't have to click a 'Send' button after making changes.  The brightness slider and the color picker use a delayed event handler, to prevent from flooding the ESP8266 web server with too many requests too quickly.
 
-The only drawback to SPIFFS that I've found so far is uploading the files can be extremely slow, requiring several minutes, sometimes regardless of how large the files are.  It can be so slow that I've been just developing the web app and debugging locally on my desktop (with a hard-coded IP for the ESP8266), before uploading to SPIFFS and testing on the ESP8266.

 Installing
 -----------
 The app is installed via the Arduino IDE which can be [downloaded here](https://www.arduino.cc/en/main/software). The ESP8266 boards will need to be added to the Arduino IDE which is achieved as follows. Click File > Preferences and copy and paste the URL "http://arduino.esp8266.com/stable/package_esp8266com_index.json" into the Additional Boards Manager URLs field. Click OK. Click Tools > Boards: ... > Boards Manager. Find and click on ESP8266 (using the Search function may expedite this). Click on Install. After installation, click on Close and then select your ESP8266 board from the Tools > Board: ... menu.
