 Now that we have a message handler, we can launch blaster to handle messages stored in a supported broker. For instance, to process messages in an AWS SQS queue called test with the script created in step 1, launch blaster with following command (this should be executed in the directory containing node script):
 
 ```
+chmod +x ./handler.js
 blaster sqs --queue-name "test" --region "ap-southeast-2" --handler-command ./handler.js
 ```
