 ## Usage
 
+
+**IMPORTANT:** The `master` branch is used in `source` just as an example. In your code, do not pin to `master` because there may be breaking changes between releases.
+Instead pin to the release tag (e.g. `?ref=tags/x.y.z`) of one of our [latest releases](https://github.com/cloudposse/terraform-aws-ec2-instance-group/releases).
+
+
 Note: add `${var.ssh_key_pair}` private key to the `ssh agent`.
 
 Include this repository as a module in your existing terraform code.
