 An implementation of the [AWS Java SDK v2 HTTP Client SPI](https://docs.aws.amazon.com/sdk-for-java/latest/developer-guide/http-configuration.html) using [the Java 11 HttpClient](https://docs.oracle.com/en/java/javase/11/docs/api/java.net.http/java/net/http/HttpClient.html).
 
 It was pulled from the [@aws/aws-java-sdk-v2](https://github.com/aws/aws-sdk-java-v2) [java-11-http-client](https://github.com/aws/aws-sdk-java-v2/tree/java-11-http-client) branch.
 
 It is very much a work in progress. Help, feedback, and PRs are all welcome and (greatly) appreciated!
 
+## Getting started
+
+To include the asynchronous client in your code, simply add the following Maven dependency:
+
+```xml
+ <dependency>
+ <groupId>com.sigpwned</groupId>
+ <artifactId>awssdkv2-java11-async-client<</artifactId>
+ <version>2.37.7.0-b0</version>
+ </depenency>
+```

 ## Background
 
 AWS Java SDK v2 has an [HTTP client service provider interface](https://central.sonatype.com/artifact/software.amazon.awssdk/http-client-spi), which it leverages to provide [a variety of managed HTTP clients](https://docs.aws.amazon.com/sdk-for-java/latest/developer-guide/http-configuration.html) (e.g., [software.amazon.awssdk:url-connection-client](https://central.sonatype.com/artifact/software.amazon.awssdk/url-connection-client)). It would be usefult to have an additional AWS HTTP Client backed by the Java 11 HttpClient for a variety of reasons:
