+# This script executes a blue/green deployment on the petclinic 
+# production infrastructure.
 # 
 # Production infrastructure consists of:
-#	- An application load balancer (prod-petclinic)
+#   - An application load balancer (prod-petclinic)
 #   - Two target groups (proda-petclinic, prodb-petclinic)
-#   - A single t2.micro ec2 instance in each target group (proda.petclinic.liatr.io, prodb.petclinic.liatr.io)
+#   - A single t2.micro ec2 instance in each target group 
 #
-# One of the two target groups should be attached to the ALB at any given time via a Listener
+# One of the two target groups should be attached to the ALB at any given timel 
+# via a Listener
 #
 # To perform a blue/green deployment, we:
-# 	- Figure out which target group is detached
-#	- Deploy the application to each instance in the detached target group (only 1 instance in this case)
-#	- Run smoke tests on the newly deployed applications
-#	- Delete the current attached listener
+#   - Figure out which target group is detached
+#   - Deploy the application to each instance in the detached target group 
+#   - Run smoke tests on the newly deployed applications
+#   - Delete the current attached listener
 #   - Attach a new listener that forwards to the target group we deployed to.
 #
 # Expected environment variables:
-#	- DEPLOY_KEY_PATH 			Private key used to shell deploy to petclinic prod instances
-#	- AWS_ACCESS_ID_ID			
-#	- AWS_SECRET_ACCESS_KEY		For modifying load balancer resources
-#   - IMAGE						Dockerhub repo to deploy from
