+# Auto Scaling Group without ELB example
+
+Configuration in this directory creates Launch Configuration and Auto Scaling Group.
+
+Data sources are used to discover existing VPC resources (VPC, subnet and security group) as well as AMI details.
+
+## 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.
