 *ESP8266FS* is a tool which integrates into the Arduino IDE. It adds a menu item to *Tools* menu for uploading the contents of sketch data directory into ESP8266 flash file system.
 
 - Download the tool: https://github.com/esp8266/arduino-esp8266fs-plugin/releases/download/0.2.0/ESP8266FS-0.2.0.zip.
-- 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/ESP8266FS/tool/esp8266fs.jar`)
-- Restart Arduino IDE
-- 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

+- If your board requires you to press a button (or other) to enter bootload mode for flashing a sketch, do that now.
 - Select Tools > ESP8266 Sketch Data Upload. This should start uploading the files into ESP8266 flash file system. When done, IDE status bar will display `SPIFFS Image Uploaded` message.
