+  Provides an Lightsail Domain 
+---
+
+# aws\_lightsail\_domain
+
+Creates a domain resource for the specified domain (e.g., example.com).
+You cannot register a new domain name using Lightsail. You must register
+a domain name using Amazon Route 53 or another domain name registrar. 
+If you have already registered your domain, you can enter its name in 
+this parameter to manage the DNS records for that domain. 
+
+~> **Note:** Lightsail is currently only supported in `us-east-1` region.
+
+## Example Usage, creating a new domain
+
+```
+resource "aws_lightsail_domain" "domain_test" {
+  domain_name = "mydomain.com"
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `domain_name` - (Required) The name of the Lightsail domain to manage
+
+## Attributes Reference
+
+The following attributes are exported in addition to the arguments listed above:
+
+* `id` - The name used for this domain
+* `arn` - The ARN of the Lightsail domain
