+## Feature aws-backend
+Will use a file `backend.dev.live.properties` where dev is the [account-name], live is the  [stage].
+
+the backend.dev.live.properties file content:
+```
+key = ".."
+region = "the aws region"
+profile = "the profile used for aws"
+bucket = "the s3 bucket name"
+kms_key_id = "the aws key id"
+```
+
+the build.py file content:
+```
+class MyBuild(AwsBackendPropertiesMixin, DevopsTerraformBuild):
