+After creating a new repository from the template and cloning locally:
+
+```bash
+./eject.sh <module-name>
+```
+
+Where `<module-name>` can be extracted from the repository name using the pattern `terraform-aws-<module-name>`.
+
+For example, if the repository name is `terraform-aws-s3-bucket`, then the module name is `s3-bucket` and the associated eject command is:
+
+```bash
+./eject.sh s3-bucket
+```
+
+Note: this message will self destruct upon ejection!
