+# Database Scripts
+
+**Simplified database initialization system for Interactive Brokers data.**
+
+## Quick Start
+
+```bash
+# Initialize everything (recommended)
+bun run db:init
+
+# Or run Interactive Brokers setup directly:
+bun run db:setup-ib   # Create schema and populate IB data
+```
+
+## What We Built
+
+✅ **Simplified from complex multi-table schema to exchanges-only**  
+✅ **Single script setup** - `setup-ib.ts` handles both schema and data  
+✅ **Structured logging** with `@stock-bot/logger`  
+✅ **184 exchanges populated** from JSON data  
+✅ **Proper error handling** with helpful troubleshooting messages  
+
+## Scripts
+
+### `setup-ib.ts` - Interactive Brokers Complete Setup
+**Main script for IB setup** - Sets up schema and populates exchange data in one go.
+
+### `init.ts`
+Main initialization script that orchestrates setup for all providers.
+
+## Database Schema
+
+### IB Data (`ib_data` schema)
+- `exchanges` - Trading exchanges with metadata
+- `upsert_exchange()` - Function to insert/update exchanges
+
+## Package.json Commands
+
+```json
+{
+  "db:init": "Run complete database initialization",
+  "db:setup-ib": "Complete IB setup (schema + data)"
+}
+```
+
+## Adding New Providers
+
+1. Create `{provider}.sql` in `database/postgres/providers/`
+2. Create `{provider}.ts` script 
+3. Add to `init.ts` and `package.json`
+
+## Requirements
+
+- PostgreSQL running
+- Database configured in `.env`
+- `ib-exchanges.json` file in `apps/data-service/src/setup/`
