+# terraform-aws-route53
+Terraform module to create route 53 hosted zones.
+
+## Usages
+
+### Example for public zone:
+
+```hcl
+module "public_zone_name" {
+    source    = "git@github.com:nimbux911/terraform-aws-route53/tags/v1.0"
+    zone_name = "name."
+
+        record_set = [ {
+        record_name = "name."
+        type        = "A" // Valid values are A, AAAA, CAA, CNAME, MX, NAPTR, NS, PTR, SOA, SPF, SRV and TXT
+        ttl         = 300 
+        records     = ["IP"]
+    } ]
+
+    tags = {
+        Environment  = var.environment
+        Purpose     = "Api endpoint"
+    }
+}
+```
+
+### Example for private zone:
+
+```hcl
+module "private_zone_name" {
+    source    = "git@github.com:nimbux911/terraform-aws-route53/tags/1.0"
+    zone_name = "name."
+    vpc_id    = "vpc-id"
+    record_set = [ {
+        record_name = "name."
+        type        = "A" // Valid values are A, AAAA, CAA, CNAME, MX, NAPTR, NS, PTR, SOA, SPF, SRV and TXT
+        ttl         = 300 
+        records     = ["IP"]
+    } ]
+
+    tags = {
+        Environment  = var.environment
+        Purpouse     = "Api endpoint"
+    }
+}
+```
+
+
+## Outputs
+
+| Name | Description |
+|------|-------------|
+| zone_id | The ID of Hosted Zone |
+| name_servers | A list of name servers in associated (or default) delegation set |
+| zone_name | Route53 Hosted Zone domain name |
