 ## Communication with remote Jobs using Redis
 This example demonstrates how HyperFlow can communicate with remote job executors using Redis. 
 
- - The workflow invokes function `submitRemoteJob` from `functions.js` 100 times. This function simulates submission of jobs by starting 100 parallel processes of `handler.js`.
+ - The workflow invokes function `submitRemoteJob` from `functions.js` 100 times. This function simulates submission of jobs by starting 100 parallel processes of `node handler.js  <taskId> <redis_url>`.
  - `handler.js` represents a remote job executor which is passed two parameters: `taskId` and `redis_url`. 
  - `handler.js` gets a `jobMessage` from HyperFlow, and then sends back a notification that the job has completed; `taskId` is used to construct appropriate Redis keys for this communication.
  - On the HyperFlow engine side, the Process Function can use two functions: `context.sendMsgToJob` to send a message to the job, and `context.jobResult` to wait for the notification. These functions return a [`Promise`](https://javascript.info/promise-basics), so the async/await syntax can be used as shown in the example.
