 ### Configure CLI
 Now that you have aws cli installed and credentials ready its time for the last step of the requirements -> configuring the aws cli to work with your account. 
 
-Open terminal in your OS and type `aws configure` and press enter. Now copy/paste the api key and secret that you got in the previous step.

For quick reference US (us-east-1,us-west-1), Europe (eu-central-1,eu-west-1), Latam (sa-east-1), Asia (ap-southeast-1).
