+## Metrics
+
+The `metric` package provides OpenTelemetry semantic-convention compliant HTTP server metric middleware:
+
+- `http.server.request.duration`
+- `http.server.active_requests`
+- `http.server.request.body.size`
+- `http.server.response.body.size`
+
+Legacy metric middleware for `request_duration_millis`, `requests_inflight`, and `response_size_bytes` is still available but deprecated.
+
 ## Why Port This?
 
 I was planning to make this project as part of the Open Telemetry Go instrumentation project. However, based on [this comment](https://github.com/open-telemetry/opentelemetry-go-contrib/pull/986#issuecomment-941280855) they no longer accept new instrumentation. This is why I maintain this project here.
