 This project shows how serverless, event-driven architectures can be used to execute code in response to messages or to handle streams of data records.
 
-It demonstrates two OpenWhisk actions (written in JavaScript) that read and write messages with Message Hub (based on Apache Kafka). The use case demonstrates how actions can work with data services and execute logic in response to message events.
+It demonstrates two IBM Cloud Functions (powered by Apache OpenWhisk) actions (written in JavaScript) that read and write messages with Message Hub (based on Apache Kafka). The use case demonstrates how actions can work with data services and execute logic in response to message events.
 
 One action receives message streams of one or more data records, and these are in turn piped to another action in an OpenWhisk sequence (a way to link actions declaratively in a chain). The second action aggregates the message and posts a transformed message to another topic.

 ## Included components
 
-- OpenWhisk
+- IB Cloud Functions powered by Apache OpenWhisk
 - IBM Message Hub (Apache Kafka)
 
 ## Prerequisites
 
 You should have a basic understanding of the OpenWhisk programming model. If not, [try the action, trigger, and rule demo first](https://github.com/IBM/openwhisk-action-trigger-rule).
 
-Also, you'll need a Bluemix account and the latest [OpenWhisk command line tool (`wsk`) installed and on your PATH](https://github.com/IBM/openwhisk-action-trigger-rule/blob/master/docs/OPENWHISK.md).

 # 1. Configure IBM Message Hub
-Log into Bluemix, provision a [Message Hub](https://console.ng.bluemix.net/catalog/services/message-hub) instance, and name it `kafka-broker`. On the "Manage" tab of your Message Hub console create two topics: _in-topic_ and _out-topic_.

 Copy `template.local.env` to a new file named `local.env` and update the `KAFKA_INSTANCE`, `SRC_TOPIC`, and `DEST_TOPIC` values for your instance if they differ.

 # Troubleshooting
-Check for errors first in the OpenWhisk activation log. Tail the log on the command line with `wsk activation poll` or drill into details visually with the [monitoring console on Bluemix](https://console.ng.bluemix.net/openwhisk/dashboard).

 If the error is not immediately obvious, make sure you have the [latest version of the `wsk` CLI installed](https://console.ng.bluemix.net/openwhisk/learn/cli). If it's older than a few weeks, download an update.

 # Alternative deployment methods
 `deploy.sh` will be replaced with [`wskdeploy`](https://github.com/openwhisk/openwhisk-wskdeploy) in the future. `wskdeploy` uses a manifest to deploy declared triggers, actions, and rules to OpenWhisk.
