+# Data Source: aws_msk_cluster
+
+Get information on an Amazon MSK Cluster.
+
+## Example Usage
+
+```hcl
+data "aws_msk_cluster" "example" {
+  cluster_name = "example"
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `cluster_name` - (Required) Name of the cluster.
+
+## Attribute Reference
+
+In addition to all arguments above, the following attributes are exported:
+
+* `arn` - Amazon Resource Name (ARN) of the MSK cluster.
+* `bootstrap_brokers` - A comma separated list of one or more hostname:port pairs of Kafka brokers suitable to boostrap connectivity to the Kafka cluster.
+* `kafka_version` - Apache Kafka version.
+* `number_of_broker_nodes` - Number of broker nodes in the cluster.
+* `tags` - Map of key-value pairs assigned to the cluster.
+* `zookeeper_connect_string` - A comma separated list of one or more IP:port pairs to use to connect to the Apache Zookeeper cluster.
