-  * If `PRIVATE_KEY_PEER` is not set the inline watcher peer will not send txs to L2 on receiving P2P network messages
+  * `PRIVATE_KEY_PEER` is used by watcher peer to send txs to L2 chain
 * NOTE:
   * Stack Orchestrator needs to be run in [`dev`](/docs/CONTRIBUTING.md#install-developer-mode) mode to be able to edit the env file
   * If Optimism is running on the host machine, use `host.docker.internal` as the hostname to access the host port
