 ## Running the example
 
-To run the example, create a Code Engine project from the Console or Code Engine CLI. Next, set the following environment variables in the shell where your Java executables run:
-```
-CE_API_KEY=<Your IBM Cloud API key>
-CE_PROJECT_ID=<Your Code Engine project ID>
-CE_PROJECT_REGION=<The region (e.g. 'us-south') of your Code Engine project>
-```
-Finally, run the `IbmCloudCodeEngineExamples` Class. 
+To run the example, create a Code Engine project from the Console or Code Engine CLI. Next, from the root directory, set the following environment variables, build the project, and execute the `IbmCloudCodeEngineExamples` class:
+1. `export CE_API_KEY=<Your IBM Cloud API key>`
+2. `export CE_PROJECT_ID=<Your Code Engine project ID>`
+3. `export CE_PROJECT_REGION=<The region (e.g. 'us-south') of your Code Engine project>`
