 # terraform-alicloud-serverless-workflow
 Terraform Module for creating Serverless Workflow resources on Alibaba Cloud.
+
+These types of resources are supported:
+
+* [alicloud_fnf_flow](https://registry.terraform.io/providers/aliyun/alicloud/latest/docs/resources/fnf_flow)
+* [alicloud_fnf_execution](https://registry.terraform.io/providers/aliyun/alicloud/latest/docs/resources/fnf_execution)
+* [alicloud_fnf_schedule](https://registry.terraform.io/providers/aliyun/alicloud/latest/docs/resources/fnf_schedule)
+
+## Usage
+
+```hcl
+module "example" {
+  source      = "terraform-alicloud-modules/serverless-workflow/alicloud"
+  description = "your_description"
+  name        = "your_name"
+  type        = "DEFAULT"
+
+  execution_name = "your_execution_name"
+  flow_name      = "your_flow_name"
+  input          = "your_input"
+  status         = "your_status"
+
+  cron_expression = "your_cron_expression"
+  schedule_name   = "your_schedule_name"
+  payload         = "your_payload"
+}
+```
