# addRules - Pricing Module Reference

This documentation provides a reference to the `addRules` method. This belongs to the Pricing Module.

## addRules(data, sharedContext?): Promise<[PriceSetDTO](../../pricing/interfaces/pricing.PriceSetDTO.mdx)>

This method adds rules to a price set.

### Example

```ts
import {
  initialize as initializePricingModule,
} from "@medusajs/pricing"

async function addRulesToPriceSet (priceSetId: string) {
  const pricingService = await initializePricingModule()

  const priceSet = await pricingService.addRules({
    priceSetId,
    rules: [{
      attribute: "region_id"
    }]
  })

  // do something with the price set or return it
}
```
