 # Example Pyth Publisher
-An example publisher demonstrating how to use the [Pyth Agent websocket API](https://docs.pyth.network/publish-data/pyth-client-websocket-api) to publish prices to Pyth. **Pyth publishers publish their own first party data to the Pyth network. This example is created solely for demonstration/testing purposes and is not used in production by any publisher.**
+An example publisher demonstrating how to use the [Pyth Agent websocket API](https://docs.pyth.network/price-feeds/publish-data/pyth-client-websocket-api) to publish prices to Pyth. **Pyth publishers publish their own first party data to the Pyth network. This example is created solely for demonstration/testing purposes and is not used in production by any publisher.**
 
 The publisher:
 - Looks up the price accounts corresponding to the configured symbols from the on-chain program.
 - Based on the configured provider, subscribes to the feeds on Pythnet, or polls the prices from Coingecko.
 - Publishes price updates for those symbols in response to `notify_price_sched` messages from Pyth Agent.
 
 ## Prerequisites
-This requires a running instance of the `pyth-agent` binary to be running. To set this up, follow the instructions in [Pyth Agent repository]([https://docs.pyth.network/publish-data](https://github.com/pyth-network/pyth-agent)). This example publisher's `publisher.pythd.endpoint` configuration value should be set to the pyth-agent websocket endpoint (e.g. `ws://127.0.0.1:8910`).
