+2. How do I find the Sui Object ID of a PriceInfoObject for a Pyth Price Feed?
+The list of Pyth price feed IDs can be found [here](https://pyth.network/developers/price-feed-ids#pyth-evm-testnet).
+
+The mapping of Pyth price feed IDs to `PriceInfoObject` object IDs can be found [here](./scripts/generated/).
+
+This mapping is also stored on-chain, and can be queried on-chain using the getter function `pyth::state::get_price_info_object_id` defined in the Pyth package.
