-Bug and Features: Please report bugs and wishes to me. Thanks!
+## Build Instructions
 
+### Prerequisites
+1. Install ESP-IDF v5.0 or later
+
+2. For ESP32-C3, ensure RISC-V toolchain is installed
+
+### Building
+
+```bash
+cd led-controller-firmware
+
+# For ESP32 DevKitC
+idf.py set-target esp32
+idf.py build
+
+# For ESP32-C3 MINI
+idf.py set-target esp32c3
+idf.py build
+```
+
+### Flashing
+
+```bash
+idf.py -p /dev/ttyUSB0 flash monitor
+```
+
+Replace `/dev/ttyUSB0` with your serial port (COM3 on Windows).
+
+## Hardware Setup
+
+### Wiring
+```
+ESP32 Pin    -> Component
+-----------     ----------
+GPIO XX      -> WS2812B Strip A Data
+GPIO XX      -> WS2812B Strip B Data
+GPIO XX      -> RC PWM Signal
+GND          -> Common Ground
+5V           -> LED Strip Power (if current < 500mA)
+```
+
+### LED Strips
+- **WS2812B** strips require 5V power
+- Each LED draws ~60mA at full white
+- Use external power supply for >10 LEDs
+- Add 100-500µF capacitor near strips
+- Add 330Ω resistor on data line
+
+### PWM Signal
+- Standard RC PWM: 1000-2000µs pulse width
+- 1500µs threshold for mode switching
+- Rising edge >1500µs after <1500µs triggers next mode
+
+## Development
+
+### Adding New Animations
+
+1. Add mode to `animation_mode_t` enum in `animation.h`
+2. Implement animation function in `animation.c`
+3. Add case to `animation_update()` switch statement
+4. Update `MODE_NAMES` array in `webapp/app/app.js`
+
+### Modifying LED Count
+
+Edit `DEFAULT_NUM_LEDS_A` and `DEFAULT_NUM_LEDS_B` in `control.c`. TODO:
+
+### Testing
+
+```bash
+# Build and flash
+idf.py build flash
+
+# Monitor output
+idf.py monitor
+
+# Exit monitor: Ctrl+]
+```
