 # Pico2W DualSense 5 Bridge
+
 [中文](./README.md)
-> Turn the Pico2W into a wireless adapter for the DS5 controller
 
-# Features
+> Turn a Raspberry Pi Pico2W into a wireless adapter for the DualSense (DS5) controller.
-- Supports HD Haptics
 
-# Usage
+## Overview
-1. Hold down the BOOTSEL button on the Pico to enter flashing mode
-2. Drag the `.uf2` file onto it
-3. Put the DS5 controller into Bluetooth pairing mode
-4. Enjoy it
 
-- Adjusting the microphone volume changes the haptic gain multiplier, range: [1, 2]
+This project enables the Raspberry Pi Pico2W to function as a Bluetooth bridge for the DualSense controller, allowing wireless connectivity with enhanced haptics support.
-- Enabling speaker mute disables the LED connection indicator (takes effect after the controller reconnects)
-- Enabling microphone mute disables silent disconnection
-- The device will only appear in the system after the controller is connected to the Pico
 
-# Current Issues
+## Features
-- Audio may have slight stuttering
-- Due to encoding requirements, the Pico needs to be overclocked. The current settings are 1.2V and 270MHz. In my own testing, the maximum stable frequency was 270MHz, with good results.
-- If your Pico cannot boot with these overclocking settings, increase the voltage or lower the frequency yourself
 
-# Future Plans
+- 🎮 Full DualSense connectivity via Pico2W
+- 🔊 Supports HD haptics (advanced vibration feedback)
+- 📡 Wireless Bluetooth bridging
+- ⚙️ Adjustable haptic gain via microphone volume
+- 🔕 Configurable LED and disconnection behaviors
 
-# Build
+## Getting Started
-You need to upgrade the TinyUSB version in the Pico SDK to the latest version

+3. The device will mount as a USB storage device
+4. Drag and drop the .uf2 firmware file onto the device
+
+### Pairing the Controller
+
+1. Put the DualSense controller into Bluetooth pairing mode
+2. Wait for the Pico2W to detect and connect
+3. Once connected, the device will appear on the host system
+
+## Configuration
+
+The following controller settings are repurposed:
+
+### Microphone volume
+
+Controls haptic gain multiplier
+
+Range: [1.0 – 2.0]
+
+### Speaker mute
+
+Disables LED connection indicator
+
+Takes effect after controller reconnects
+
+### Microphone mute
+
+Disables silent disconnection behavior
+
+## Notes
+
+The Pico device will only be visible to the system after the controller is connected
+
+Some behaviors depend on reconnection cycles to take effect
+
+## Known Issues
+
+- ⚠️ Audio may experience slight stuttering
+- ⚠️ Overclocking is required for proper performance
+
+## Performance / Overclocking
+
+Due to encoding requirements, the Pico2W must be overclocked:
+
+Current settings:
+
+- Voltage: 1.2V
+- Frequency: 320 MHz
+
+If your device fails to boot:
+
+- Increase voltage slightly or Reduce CPU frequency
+
+## Build Instructions
+
+To build the project from source:
+
+1. Update TinyUSB in the Pico SDK to the latest version
+2. Compile using standard Pico SDK toolchain
+
+## Roadmap
+
+- Improve audio stability
