+When using the `workflow_dispatch` event, you can optionally specify inputs that are passed to the workflow.
+
+The triggered workflow receives the inputs in the `github.event.inputs` context. For more information, see "[Contexts](/actions/learn-github-actions/contexts#github-context)."
+
+```yaml
