+# Step Group
+
+## How to start
+
+Edit a yaml file as `example.yaml`, then execute it with `vela up` command.
+
+## Parameter Introduction
+
+`step-group` has a `subSteps` parameter which is an array containing any step type whose valid parameters do not include the `step-group` step type itself.
+
+`step-group` doesn't support `properties` for now.
+
+## Execute process
+
+When executing the `step-group` step, the subSteps in the step group are executed in dag mode. The step group will only complete when all subSteps have been executed to completion.
+SubStep has the same execution behavior as a normal step.
