+# Ruby AWS Sigv4 Client
+
+The [opensearch-aws-sigv4](https://github.com/opensearch-project/opensearch-ruby/tree/main/opensearch-aws-sigv4) gem provides the `OpenSearch::Aws::Sigv4Client` class, which has all features of `OpenSearch::Client`. The only difference between these two clients is that `OpenSearch::Aws::Sigv4Client` requires an instance of `Aws::Sigv4::Signer` during instantiation to authenticate with AWS:
+
+```ruby
+require 'opensearch-aws-sigv4'
+require 'aws-sigv4'
+
+signer = Aws::Sigv4::Signer.new(service: 'es',
+                                region: 'us-west-2',
+                                access_key_id: 'key_id',
+                                secret_access_key: 'secret')
+
+client = OpenSearch::Aws::Sigv4Client.new({ log: true }, signer)
+
+client.cluster.health
+
+client.transport.reload_connections!
+
+client.search q: 'test'
+```
