+## Use Instrumentation Libraries
+
+Each instrumentation library is a [crate](https://crates.io/).
+
+For example, the
+[instrumentation library for Actix Web](https://crates.io/crates/actix-web-opentelemetry)
+will automatically create [spans](/docs/concepts/signals/traces/#spans) and
+[metrics](/docs/concepts/signals/metrics/) based on the inbound HTTP requests.
+
+For a list of available instrumentation libraries, see the
+[registry](/ecosystem/registry/?language=rust&component=instrumentation).
