 # terraform-alicloud-elasticsearch-instance
 Terraform module which creates ElasticSearch Instances on Alibaba Cloud
+
+These types of resources are supported:
+
+* [Alicloud_elasticsearch_instance](https://www.terraform.io/docs/providers/alicloud/r/elasticsearch.html)
+
+Root module calls these modules which can also be used separately to create independent resources:
+
+* [instance](https://github.com/terraform-alicloud-modules/terraform-alicloud-elasticsearch-instance/tree/master/modules/instance) - creates Elasticsearch instance
+
+Usage
+-----
+You can use this in your terraform template with the following steps.
+
+1. Adding a module resource to your template, e.g. main.tf
+
+        module "instance" {
+          source = "terraform-alicloud-modules/elasticsearch-instance/alicloud"
+          password = "Your password"
+          data_node_spec = "elasticsearch.sn2ne.large"
+          data_node_amount = "2"
+          data_node_disk_size = "20"
+          data_node_disk_type = "cloud_ssd"
+          es_version = "5.5.3_with_X-Pack"
+          vswitch_id = "vswitch id"
+        }
+
+2. Setting values for the following variables through environment variables:
+
+    - ALICLOUD_ACCESS_KEY
+    - ALICLOUD_SECRET_KEY
+    - ALICLOUD_REGION
+
+# alicloud_elasticsearch_instance
