 Example above will set environmental variable `FOO_MY_PARAMETER_NAME` with value from the AWS SSM parameter itself.
 
+##### Skipping the prefix
+
+It's also possible to completely skip prefixing environmental variables by using `skip_prefix` parameter:
+```yaml
+name: Parse SSM parameter

+on:
+  push

+jobs:
+  aws-ssm-to-env:
+    runs-on: ubuntu-latest
+    steps:
