+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+This is a target configuration management system for the QUICKSILVER Flight Controller Firmware. It manages hardware target definitions for 500+ FPV flight controller boards, converting Betaflight unified targets to QUICKSILVER-compatible YAML format and generating target indices.
+
+## Development Commands
+
+```bash
+# Convert Betaflight configs to staging targets
+npm run translate
+
+# Build target index and validate configurations  
+npx vite-node src/index.ts
+
+# Sync specific fields between staging and production targets
+npx vite-node src/sync.ts
+
+# Install dependencies
+npm install
+```
+
+## Architecture Overview
+
+**Core Components:**
+- `src/translate.ts` - Converts Betaflight `config.h` files to QUICKSILVER YAML format
+- `src/index.ts` - Processes all target YAML files and generates consolidated indices
+- `src/dma.ts` - Automatically assigns DMA channels and prevents hardware conflicts
+- `src/sync.ts` - Syncs specific fields between staging and production targets
+
+**Directory Structure:**
+- `targets/` - Production target configurations (500+ YAML files)
+- `staging/` - Converted Betaflight targets awaiting validation
+- `betaflight/` - Git submodule with upstream Betaflight configurations
+- `mcu/` - MCU-specific pin and DMA definitions (stm32f405, stm32f411, etc.)
+- `manufacturers.yaml` - Manufacturer database with codes and metadata
+
+**Target Configuration Format:**
+Each target YAML contains hardware definitions: MCU type, pin mappings, serial/SPI ports, gyro configuration, motor outputs, and DMA assignments. Files are validated against `src/schema/target.json`.
+
+**MCU Support:**
+STM32F405/F411/F722/F745/F765/H743, STM32G473, AT32F435 with MCU-specific pin definitions in `mcu/{type}/gpio.yaml` and DMA mappings in `mcu/{type}/dma.yaml`.
+
+**CI/CD Pipeline:**
+Automated builds on master push generate target indices and deploy to the `targets` branch for consumption by QUICKSILVER firmware builds.
