+The [scheduler](https://github.com/pyth-network/pyth-crosschain/tree/main/apps/price_pusher) (previously known as "price pusher")
 is an off-chain application that regularly pulls price updates on to a blockchain.
 Anyone can run this service to regularly update the on-chain Pyth price based on various conditions, such as a minimum update frequency, or a price change threshold.
 This service can simplify the process of migrating to Pyth from other oracles.
