+Complete RDS example
+====================
+
+Configuration in this directory creates set of RDS resources including DB instance, DB subnet group and DB parameter group.
+
+Data sources are used to discover existing VPC resources (VPC, subnet and security group).
+
+Usage
+=====
+
+To run this example you need to execute:
+
+```bash
+$ terraform init
+$ terraform plan
+$ terraform apply
+```
+
+Note that this example may create resources which cost money. Run `terraform destroy` when you don't need these resources.
