+# Route53 Terraform module
+
+Terraform module which creates Route53 resources.
+
+There are independent submodules:
+
+* [zones](https://github.com/terraform-aws-modules/terraform-aws-route53/tree/master/modules/zones) - to manage Route53 zones
+* [records](https://github.com/terraform-aws-modules/terraform-aws-route53/tree/master/modules/records) - to manage Route53 records
+
+This module currently does not have all arguments supported by the Terraform AWS providers.
+
+
+## Terraform versions
+
+Terraform 0.12. Pin module version to `~> v1.0`. Submit pull-requests to `master` branch.
+
+
+## Usage
+
+### Create Route53 zones and records
+
+```hcl
+module "zones" {
+  source  = "terraform-aws-modules/route53/aws//modules/zones"
+  version = "~> 1.0"
+
+  zones = {
+    "terraform-aws-modules-example.com" = {
+      comment = "terraform-aws-modules-examples.com (production)"
+      tags = {
+        env = "production"
+      }
+    }
+
+    "myapp.com" = {
+      comment = "myapp.com"
+    }
+  }
+}
+
+module "records" {
+  source  = "terraform-aws-modules/route53/aws//modules/records"
+  version = "~> 1.0"
+
+  zone_name = keys(module.zones.this_route53_zone_zone_id)[0]
+
+  records = [
+    {
+      name    = "apigateway1"
+      type    = "A"
+      alias   = {
+        name    = "d-10qxlbvagl.execute-api.eu-west-1.amazonaws.com"
+        zone_id = "ZLY8HYME6SFAD"
+      }
+    },
+    {
+      name    = ""
+      type    = "A"
+      ttl     = 3600
+      records = [
+        "10.10.10.10",
+      ]
+    },
+  ]
+
+  depends_on = [module.zones]
+}
+```
+
+Note that `depends_on` in modules is available since Terraform 0.13.
+
+
+## Examples
+
+* [Complete Route53 zones and records example](https://github.com/terraform-aws-modules/terraform-aws-route53/tree/master/examples/complete)
+
+
+## Conditional creation
+
+Sometimes you need to have a way to create resources conditionally but Terraform does not allow to use `count` inside `module` block, so the solution is to specify argument `create`.

+# Route53 zones and records example
+
+Configuration in this directory creates Route53 zones and records.
+
+## Usage
+
+To run this example you need to execute:
+
+```bash
+$ terraform init
+$ terraform plan
+$ terraform apply
+```
+
+Note that this example may create resources which cost money. Run `terraform destroy` when you don't need these resources.
