sigv4/README.md

github.com/prometheus/sigv4 module

sigv4 provides a http.RoundTripper that will sign requests using Amazon's Signature Verification V4 signing procedure, using credentials from the default AWS credential chain.

This is a separate module from github.com/prometheus/common to prevent it from having and propagating a dependency on the AWS SDK.

This module is considered internal to Prometheus, without any stability guarantees for external usage.
