+## Quick Start Guide
+Install and have your USB Rubber Ducky working in less than 5 minutes.
+
+1. Start on the [Releases](https://github.com/dbisu/pico-ducky/releases) page.
+
+2. Plug the device into a USB port while holding the boot button. It will show up as a removable media device named RPI-RP2.
+
+3. Install CircutlPython on the Pico or Pico W
+
+If using a Pico board:
+
+Copy the adafruit-circuitpython-raspberry_pi_pico-en_US-8.0.0.uf2 file to the root of the Pico (RPI-RP2). The device will reboot and after a second or so, it will reconnect as CIRCUITPY.
+
+If using a Pico W board:
+
+Copy the adafruit-circuitpython-raspberry_pi_pico_w-en_US-8.0.0.uf2 file to the root of the Pico (RPI-RP2). The device will reboot and after a second or so, it will reconnect as CIRCUITPY.
+
+4. Copy the lib folder to the root of the CIRCUITPY
+
+5. Copy *.py to the root of the CIRCUITPY
+
+6. Follow the instructions in README.md to enter setup mode
+
+7. Copy your payload as payload.dd to the root of the CIRCUITPY
+
+8. Unplug the device from the USB port and remove the setup jumper.
+
+Enjoy your Pico-Ducky.
+
+## Setup mode
+
+To edit the payload, enter setup mode by connecting the pin 1 (`GP0`) to pin 3 (`GND`), this will stop the pico-ducky from injecting the payload in your own machine.
+The easiest way to do so is by using a jumper wire between those pins as seen bellow.
+
+![Setup mode with a jumper](images/setup-mode.png)
+
+## USB enable/disable mode
+
+If you need the pico-ducky to not show up as a USB mass storage device for stealth, follow these instructions.  
+- Enter setup mode.    
+- Copy your payload script to the pico-ducky.  
+- Disconnect the pico from your host PC.
+- Connect a jumper wire between pin 18 (`GND`) and pin 20 (`GPIO15`).  
+This will prevent the pico-ducky from showing up as a USB drive when plugged into the target computer.  
+- Remove the jumper and reconnect to your PC to reprogram.  
+
+Pico: The default mode is USB mass storage enabled.   
+Pico W: The default mode is USB mass storage **disabled**
