1. From "Installing an AWS Load Balancer Operator" section, all the instructions for creating objects with "cat" command need improvement 

2. "<<" symbols are missing so that the command is always returning error messages without success, which could confuse customer who is following these steps.

3. Need improvement on creating "Subscription" and "AWSLoadBalancerController" Objects in documentation.
