"Describe your use-case which is not covered by existing documentation."

What "existing documentation"? Am I missing something, or does this not exist? There's barely any content on these pages -

https://plugins.jenkins.io/aws-credentials/

https://wiki.jenkins-ci.org/display/JENKINS/CloudBees-AWS-Credentials-Plugin.html

https://github.com/jenkinsci/aws-credentials-plugin#readme

https://docs.cloudbees.com/plugins/ci/aws-credentials

### Reference any relevant documentation, other materials or issues/pull requests that can be used for inspiration.

Review the README and the linked Jenkins, CloudBees, and plugin documentation pages to determine what usage information is missing. Define a focused documentation scope, add instructions for using the AWS Credentials Plugin, and verify that the relevant pages provide a consistent getting-started path.
