-## Using the AWS SDK vendored in the AWS cloudprovider
-
-If you want to use a newer version of the AWS SDK than the version currently vendored as a direct dependency by Cluster Autoscaler, then you can use the version vendored under this AWS cloudprovider.
-
-The current version vendored is `v1.48.7`.
-
-If you want to update the vendored AWS SDK to a newer version, please make sure of the following:
-
-1. Place the copy of the new desired version of the AWS SDK under the `aws-sdk-go` directory.
-2. Remove folders : models and examples. Remove _test.go file `find . -name '*_test.go' -exec rm {}+`
-3. Update the import statements within the newly-copied AWS SDK to reference the new paths (e.g., `github.com/aws/aws-sdk-go/aws/awsutil` -> `k8s.io/autoscaler/cluster-autoscaler/cloudprovider/aws/aws-sdk-go/aws/awsutil`). You can use this command from the aws-sdk-go folder `find . -type f -exec sed -i ‘s#github.com/aws/aws-sdk-go#k8s.io/autoscaler/cluster-autoscaler/cloudprovider/aws/aws-sdk-go#’ {} \;`
-4. Update the version number above to indicate the new vendored version.
