Hi,  
I am new to terraform, I am trying to create AWS DMS resources with Terraform  
first challenge was that I have AWS DMS Replication Instance that is manually created and I need to use it for creating new AWS DMS tasks.  
I have seen that data source is not supported for this resource so I tried importing it and succeeded but when I run terraform plan it fails on ARN of AWS DMS replication instance  
means that I cant use it in my AWS DMS task.tf file since aws dms replication instance not created by terraform  
bottom line my question is how can I use existing aws resources with new terraform code  
if it is by import what are the steps to do it?
