## How it works

Add a few lines to your code and LangWatch starts tracking everything:

1. **Add the SDK** - Drop in a few lines of code to your existing app
2. **We track everything** - Automatically captures all your LLM calls and interactions
3. **See it live** - Watch what's happening in real-time through the dashboard
4. **Debug easily** - Click into any trace to see exactly what went wrong
