 Terraform version
 -----------------
-Terraform version 0.12.0 or newer and Provider version 1.77.0 or newer are required for this example to work.
+| Name | Version |
+|------|---------|
+| <a name="requirement_terraform"></a> [terraform](#requirement\_terraform) | >= 0.12.0 |
+| <a name="requirement_alicloud"></a> [alicloud](#requirement\_alicloud) | >= 1.56.0
+
+## Notes
+From the version v1.5.0, the module has removed the following `provider` setting:
+
+```hcl
+provider "alicloud" {
+  profile                 = var.profile != "" ? var.profile : null
+  region                  = var.region != "" ? var.region : null
+  skip_region_validation  = var.skip_region_validation
+}
+```
+
+If you still want to use the `provider` setting to apply this module, you can specify a supported version, like 1.4.0:
+
+```hcl
+module "managed-kubernetes" {
+   source = "terraform-alicloud-modules/managed-kubernetes/alicloud"
+   version     = "1.4.0"
+   region      = "cn-hangzhou"
+   profile     = "Your-Profile-Name"
+   k8s_name_prefix = "my-managed-k8s-with-new-vpc"
+   new_vpc         = true
+   vpc_cidr        = "192.168.0.0/16"
+}
+```
+
+If you want to upgrade the module to 1.5.0 or higher in-place, you can define a provider which same region with
+previous region:
+
+```hcl
+provider "alicloud" {
+   region  = "cn-hangzhou"
+   profile = "Your-Profile-Name"
+}
+module "managed-kubernetes" {
+  source = "terraform-alicloud-modules/managed-kubernetes/alicloud"
+  k8s_name_prefix = "my-managed-k8s-with-new-vpc"
+  new_vpc         = true
+  vpc_cidr        = "192.168.0.0/16"
+}
+```
+or specify an alias provider with a defined region to the module using `providers`:
+
+```hcl
+provider "alicloud" {
+  region  = "cn-hangzhou"
+  profile = "Your-Profile-Name"
+  alias   = "hz"
+}
+module "managed-kubernetes" {
+  source  = "terraform-alicloud-modules/managed-kubernetes/alicloud"
+  providers = {
+    alicloud = alicloud.hz
+  }
+   k8s_name_prefix = "my-managed-k8s-with-new-vpc"
+   new_vpc         = true
+   vpc_cidr        = "192.168.0.0/16"
+}
+```
+
+and then run `terraform init` and `terraform apply` to make the defined provider effect to the existing module state.
