+- npm or yarn
+
+### Installation
+
+```bash
+npm install
+```
+
+## Development
+
+### Available Scripts
+
+- `npm run build` - Compile TypeScript to JavaScript
+- `npm run type-check` - Run TypeScript type checking without emitting files
+- `npm run lint` - Run ESLint on TypeScript files
+- `npm run lint:fix` - Run ESLint with auto-fix
+- `npm run format` - Format code with Prettier
+- `npm run format:check` - Check if code is formatted correctly
+
+### Project Structure
+
+```
+src/
+  handlers/          # Lambda function handlers
+    vehicleType.ts   # Vehicle type lookup handler
+    scrub.ts         # Estimate scrubbing handler
+    emsupload.ts     # File upload presigned URL handler
+  lib/               # Shared library code
+    vehicleTypes/    # Vehicle type utilities
+    db.ts            # Database utilities

+
+## Deployment
+
+The project uses `serverless-esbuild` for bundling TypeScript code for deployment.
+
+```bash
+# Deploy to dev stage
+sls deploy --stage dev
+
+# Deploy to production
+sls deploy --stage prod
+```
+
+## Local Development
+
+```bash
+# Run serverless offline
+sls dev
+```
+
+## Configuration
+
+- **TypeScript**: Configured in `tsconfig.json`
+- **ESLint**: Configured in `eslint.config.mjs` (ESM flat config)
+- **Prettier**: Configured in `.prettierrc.json`
+- **Serverless**: Configured in `serverless.yml`
+
+## Code Quality
+
+This project enforces:
+- TypeScript strict mode
+- ESLint rules for TypeScript
+- Prettier formatting
+- No unused variables or parameters (except those prefixed with `_`)
