+### builder_blueprint_import_file
+
+Type: string
+Required: false
+
+Local path to the blueprint TOML file that will be used. That will be done instead of creating a new blueprint using the `builder_compose_pkgs` and `builder_compose_customizations` variables. The Blueprint name will be overwritten by the `builder_blueprint_name` variable.
+
+Example:
+
+```yaml
+builder_blueprint_import_file: "~/microshift-embedded.toml"
+```
