All existing SmartContract functions remain unchanged. New utilities are additive:

```javascript
// Existing functionality still works
const covenant = SmartContract.createCovenant(privateKey)
const preimage = SmartContract.extractPreimage(preimageHex)

// New utilities available
const asm = SmartContract.scriptToASM(scriptBuffer)
const metrics = SmartContract.scriptMetrics(script)
const explanation = SmartContract.explainScript(script)
```

### For New Users
Start with the [QUICK_START.md](./QUICK_START.md) guide for the fastest path to building covenants.
