+# Quick Start Guide
+
+Get your ESP32 8-channel relay controller up and running in 15 minutes!
+
+## What You Need
+
+- ESP32 development board
+- 8-channel relay module (5V)
+- 8+ jumper wires (male-to-female)
+- USB cable for ESP32
+- Computer with Arduino IDE
+
+## Step 1: Wire It Up (5 minutes)
+
+### Power Connections
+```
+ESP32 5V  ──→ Relay Module VCC
+ESP32 GND ──→ Relay Module GND
+```
+
+### GPIO Connections (Default Configuration)
+```
+ESP32 GPIO → Relay Module
+------------------------
+GPIO 13    → IN1
+GPIO 12    → IN2
+GPIO 14    → IN3
+GPIO 27    → IN4
+GPIO 26    → IN5
+GPIO 25    → IN6
+GPIO 33    → IN7
+GPIO 32    → IN8
+```
+
+**Quick Tip:** Use different colored wires to avoid confusion!
+
+## Step 2: Install Software (5 minutes)
+
+### Option A: Arduino IDE (Recommended for Beginners)
+
+1. **Install ESP32 Board Support**
+   ```
+   File → Preferences → Additional Board Manager URLs
+   Add: https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json
+   
+   Tools → Board → Board Manager → Search "ESP32" → Install
+   ```
+
+2. **Configure Board**
+   ```
+   Tools → Board → "ESP32 Dev Module"
+   Tools → Upload Speed → "115200"
+   ```
+
+3. **Open the Sketch**
+   - Open `esp32_bluetooth_relay.ino`
+
+### Option B: PlatformIO (For Advanced Users)
+
+```bash
+# Navigate to project folder
+cd esp32-bluetooth-relay
+
+# Build and upload
+pio run --target upload
+
+# Monitor serial output
+pio device monitor
+```
+
+## Step 3: Upload Code (2 minutes)
+
+1. Connect ESP32 to computer via USB
+2. Select correct COM port: `Tools → Port`
+3. Click **Upload** button (→)
+4. Wait for "Done uploading" message
+
+**Troubleshooting Upload:**
+- Hold BOOT button on ESP32 while uploading starts
+- Try different USB cable/port
+- Check driver installation
+
+## Step 4: Test Connection (3 minutes)
+
+### On Mobile (Easiest)
+
+1. **Download a Bluetooth Terminal App**
+   - Android: "Serial Bluetooth Terminal"
+   - iOS: "Bluetooth Terminal"
+
+2. **Pair and Connect**
+   - Open Bluetooth settings
+   - Look for "ESP32-Relay-8CH"
+   - Pair (PIN: 1234 if asked)
+
+3. **Open Terminal App**
+   - Connect to ESP32-Relay-8CH
+   - Type: `STATUS` (press Enter)
+   - You should see relay status!
+
+### On Computer
+
+**Windows:**
+1. Pair with ESP32 via Bluetooth settings
+2. Note the COM port number
+3. Open PuTTY or Arduino Serial Monitor
+4. Connect to the COM port at 115200 baud
+
+**Linux:**
+```bash
+# Find ESP32 MAC address
+hcitool scan
+
+# Pair
+bluetoothctl
+> pair XX:XX:XX:XX:XX:XX
+> trust XX:XX:XX:XX:XX:XX
+> connect XX:XX:XX:XX:XX:XX
+
+# Connect with screen or minicom
+sudo rfcomm bind /dev/rfcomm0 XX:XX:XX:XX:XX:XX
+screen /dev/rfcomm0 115200
+```
+
+## First Commands to Try
+
+```
+STATUS      # See all relay states
+ON1         # Turn on relay 1
+OFF1        # Turn off relay 1
+TOGGLE1     # Toggle relay 1
+ALL_ON      # Turn all relays on
+ALL_OFF     # Turn all relays off
+HELP        # Show all commands
+```
+
+## Quick Troubleshooting
+
+### "Can't find ESP32-Relay-8CH"
+- Power cycle the ESP32
+- Check if Bluetooth is enabled on your device
+- Unpair and re-pair if previously connected
+- Check Serial Monitor for "Bluetooth device ready" message
+
+### "Relays not switching"
+- Verify wiring matches the pin assignments
+- Check relay module power (VCC and GND)
+- Try different GPIO pins
+- Test with multimeter
+
+### "Upload failed"
+- Hold BOOT button during upload
+- Check USB cable (data cable, not charge-only)
+- Install CP210x or CH340 drivers
+- Try different USB port
+
+### "Wrong direction" (relay ON when should be OFF)
+- Your relay module is Active HIGH
+- Change code in `setRelay()` function:
+  ```cpp
+  digitalWrite(relayPins[relayIndex], state ? HIGH : LOW);
+  ```
+
+## Safety First! ⚠️
+
+**Before connecting any loads:**
+1. ✅ Test with low voltage (12V DC LED strip, for example)
+2. ✅ Verify relay is switching correctly
+3. ✅ Double-check wiring
+4. ✅ Use proper fuses
+5. ⚠️ NEVER work on AC wiring while powered
+
+**For AC loads:**
+- Consider hiring an electrician
+- Use proper electrical enclosures
+- Follow local electrical codes
+- Add fuses or circuit breakers
+
+## What's Next?
+
+### Customize Your Setup
+- Edit relay names in code
+- Change GPIO pins if needed
+- Modify Bluetooth device name
+- Add custom commands
+
+### Integration Ideas
+- Control via Home Assistant
+- Add scheduling/timers
+- Create scenes (groups of relays)
+- Add web interface
+- MQTT integration
+
+### Upgrade Options
+- Add WiFi control
+- Use ESPHome firmware
+- Add temperature sensors
+- Energy monitoring
+- Remote access via VPN
