+# aws_cloudwatch_log_resource_policy
+
+Provides a resource to manage a CloudWatch log resource policy.
+
+## Example Usage
+
+### Route53 Query Logging
+
+```hcl
+data "aws_iam_policy_document" "route53-query-logging-policy" {
+  statement {
+    actions = [
+      "logs:CreateLogStream",
+      "logs:PutLogEvents",
+    ]
+
+    resources = ["arn:aws:logs:*:*:log-group:/aws/route53/*"]
+
+    principals {
+      identifiers = ["route53.amazonaws.com"]
+      type        = "Service"
+    }
+  }
+}
+
+resource "aws_cloudwatch_log_resource_policy" "route53-query-logging-policy" {
+  policy_document = "${data.aws_iam_policy_document.route53-query-logging-policy.json}"
+  policy_name     = "route53-query-logging-policy"
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `policy_document` - (Required) Details of the resource policy, including the identity of the principal that is enabled to put logs to this account. This is formatted as a JSON string. Maximum length of 5120 characters.
+* `policy_name` - (Required) Name of the resource policy.
+
+## Attributes Reference
+
+The following additional attributes are exported:
+
+* `id` - The name of the CloudWatch log resource policy
+
+## Import
+
+CloudWatch log resource policies can be imported using the policy name, e.g.
+
+```
+$ terraform import aws_cloudwatch_log_resource_policy.MyPolicy MyPolicy
+```
