+# Arduino ESP8266 LittleFS Filesystem Uploader
+
+Arduino plugin which packs sketch data folder into LittleFS filesystem image,
+and uploads the image to ESP8266 flash memory.
+<br>
+
+## Installation
+- Make sure you use one of the supported versions of Arduino IDE and have ESP8266 core installed.
+- Download the tool archive from (https://github.com/earlephilhower/arduino-esp8266littlefs-plugin/releases).
+- In your Arduino sketchbook directory, create tools directory if it doesn't exist yet.
+- Unpack the tool into tools directory (the path will look like `<home_dir>/Arduino/tools/ESP8266LittleFS/tool/esp8266littlefs.jar)`.
+- Restart Arduino IDE. 
+
+On the OS X create the tools directory in ~/Documents/Arduino/ and unpack the files there
+
+## Usage
+- Open a sketch (or create a new one and save it).
+- Go to sketch directory (choose Sketch > Show Sketch Folder).
+- Create a directory named `data` and any files you want in the file system there.
+- Make sure you have selected a board, port, and closed Serial Monitor.
+- Select *Tools > ESP8266 LittleFS Data Upload* menu item. This should start uploading the files into ESP8266 flash file system.
+  When done, IDE status bar will display LittleFS Image Uploaded message. Might take a few minutes for large file system sizes.
