-### Recent News
-
-#### Long-term credentials warning (10/3/23)
-
-We have added a warning when using long-term credentials to access AWS
-(IAM access keys and secret keys). Using long-term credentials requires you
-to create IAM users and properly secure the access keys to prevent their disclosure.
-A better approach is to use [GitHub's support for OpenID Connect](#OIDC) to authenticate
-using an IAM role to generate temporary security credentials.
-
-#### v4 Announcement (9/11/23)
-
-We have just released `v4` of Configure AWS Credentials. The only thing that
-changed from `v3` is that the action now runs on `node20` instead of `node16`. If using a self-hosted runner, specify [v2.311.0](https://github.com/actions/runner/releases/tag/v2.311.0) or above for `node20` support.
-You can still see the `v3` announcement below, as it is still recent.
-
-#### v3 Announcement (8/23/23)
-
-We have recently released `v3` of Configure AWS Credentials! With this new
-release we have migrated the code to TypeScript, and have also migrated away
-from using `v2` of the JavaScript AWS SDK. This should eliminate the warning you
-have seen in your workflow logs about `v2` deprecation.
-
-In addition to the refactored codebase, we have also introduced some changes to
-existing functionality, added some new features, and fixed some bugs. These
-changes should be backwards compatible with your existing workflows.
-
-**Notable changes to existing functionality**
-
- By default, the assumed role credentials will only be valid for one hour in
-_all_ use cases. This is changed from 6 hours in `v2`. You can adjust this value
-with the `role-duration-seconds` input.
- By default, your account ID will not be masked in workflow logs. This was
-changed from being masked by default in the previous version. AWS does not consider
-account IDs as sensitive information, so this change reflects that stance. You
-can revert to the old default and mask your account ID in workflow logs by
-setting the `mask-aws-account-id` input to `true`.
-
-**New features**
-
- You can now configure retry settings in case your STS call fails. By default,
-we retry with exponential backoff twelve times. You can disable this behavior
-altogether by setting the `disable-retry` input to `true`, or you can configure
-the number of times the action will retry with the `retry-max-attempts` input.
- You can now set the returned credentials as action step outputs. To do this,
-you can set the `output-credentials` prop to `true`.
- There's now an option to clear the AWS-related environment variables at the
-start of the action. Clearing these variables is often a workaround for 
-problems, so enabling this can be helpful if existing credentials or environment
-variables are interfering with the action. You can enable this by setting the
-`unset-current-credentials` input to `true`.
-
-**Bug fixes**
-
-You can find a list of bugs that have been fixed in v3 in the
-[changelog](./CHANGELOG.md).

+This action implements the AWS JavaScript SDK credential resolution chain
+and exports session environment variables for your other Actions to use.
+Environment variable exports are detected by both the AWS SDKs and the AWS CLI
+for AWS API calls.

 ## Overview
+API calls to AWS need to be signed with credential information, so when you use
+one of the AWS SDKs or an AWS tool, you must provide it with AWS credentials and
+and AWS region. One way to do that in GitHub Actions is to use a repository
+secret with IAM credentials, but this doesn't follow [AWS security
+guidelines](https://docs.aws.amazon.com/IAM/latest/UserGuide/security-creds.html)
+on using long term credentials. Instead, we recommend that you use a long term
+credential or JWT to fetch a temporary credential, and use that with your tools
+instead. This GitHub Action facilitates just that.
+
+AWS SDKs and Tools look for your credentials in standardized environment
+variables. In essence, this Action runs through the standard [credential
+resolution flow](https://docs.aws.amazon.com/sdkref/latest/guide/standardized-credentials.html),
+and at the end, exports environment variables for you to use later.
+
 We support five methods for fetching credentials from AWS, but we recommend that
 you use GitHub's OIDC provider in conjunction with a configured AWS IAM
 Identity Provider endpoint.

-To do that, you would add the following step to your workflow:
-
-```yaml
-    - name: Configure AWS Credentials
-      uses: aws-actions/configure-aws-credentials@v4
-      with:
-        role-to-assume: arn:aws:iam::123456789100:role/my-github-actions-role
-        aws-region: us-east-2
-```
-This will cause the action to perform an [`AssumeRoleWithWebIdentity`](https://docs.aws.amazon.com/STS/latest/APIReference/API_AssumeRoleWithWebIdentity.html) call and
-return temporary security credentials for use by other steps in your workflow. In order for
-this to work, you'll need to preconfigure the IAM Identity Provider in your AWS account
-(see the [OIDC](https://github.com/aws-actions/configure-aws-credentials#OIDC) section below for details).
-
-You can use this action with the AWS CLI available in
-[GitHub's hosted virtual environments](https://help.github.com/en/actions/reference/software-installed-on-github-hosted-runners) or run this action multiple times
-to use different AWS accounts, regions, or IAM roles in the same GitHub Actions
-workflow. As an example, here is a complete workflow file that uploads artifacts
-to Amazon S3.
-
-```yaml
-jobs:
-  deploy:
-    name: Upload to Amazon S3
-    runs-on: ubuntu-latest
-    # These permissions are needed to interact with GitHub's OIDC Token endpoint.
-    permissions:
-      id-token: write

-        aws-region: us-east-1
-    - name: Copy files to the test website with the AWS CLI
-      run: |
-        aws s3 sync . s3://my-s3-test-website-bucket
-    - name: Configure AWS credentials from Production account
-      uses: aws-actions/configure-aws-credentials@v4

-        role-to-assume: arn:aws:iam::222222222222:role/my-github-actions-role-prod
-        aws-region: us-west-2
-    - name: Copy files to the production website with the AWS CLI

+to get short-lived AWS credentials needed for your actions. When using OIDC, you
+configure IAM to accept JWTs from GitHub's OIDC endpoint. This action will
+then create a JWT unique to the workflow run using the OIDC endpoint, and it
+will use the JWT to assume the specified role with short-term credentials. 
+
+To get this to work
+1. Configure your workflow to use the `id-token: write` permission.
+2. Configure your audience, if required.
+3. In your AWS account, configure IAM to trust GitHub's OIDC identity provider.
+4. Configure an IAM role with appropriate claim limits and permission scope.
+

+5. Specify that role's ARN when setting up this action.

 ### Claims and scoping permissions
-To align with the Amazon IAM best practice of [granting least privilege](https://docs.aws.amazon.com/IAM/latest/UserGuide/best-practices.html#grant-least-privilege), the assume role policy document should contain a [`Condition`](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_condition.html) that specifies a subject (`sub`) allowed to assume the role. [GitHub also recommends](https://docs.github.com/en/actions/deployment/security-hardening-your-deployments/about-security-hardening-with-openid-connect#defining-trust-conditions-on-cloud-roles-using-oidc-claims) filtering for the correct audience (`aud`).

However, scoping it down to your org and repo may cause the role assumption to fail in some cases.

If you aren't sure what your subject (`sub`) key is, you can add the [`actions-oidc-debugger`](https://github.com/github/actions-oidc-debugger) action to your workflow to see the value of the subject (`sub`) key, as well as other claims.
