+- Download the tool archive from [releases page](https://github.com/me-no-dev/EspExceptionDecoder/releases/latest).
+- 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/EspExceptionDecoder/tool/EspExceptionDecoder.jar)`.
+- Restart Arduino IDE.
+
+## Usage
+- Open a sketch and build it.
+- Upload the sketch and monitor the Serial port for Exceptions
+- When you get an Exception, open *Tools > ESP Exception Decoder* menu item. This will open a new window.
