+# Experimental Features
+
+The metric SDK contains features that have not yet stabilized in the OpenTelemetry specification.
+These features are added to the OpenTelemetry Go metric SDK prior to stabilization in the specification so that users can start experimenting with them and provide feedback.
+
+These feature may change in backwards incompatible ways as feedback is applied.
+See the [Compatibility and Stability](#compatibility-and-stability) section for more information.
+
+## Features
+
+- [Self-Observability](#self-observability)
+
+### Self-Observability
+
+The SDK provides a self-observability feature that allows you to monitor the SDK itself.
+
+To opt-in, set the environment variable `OTEL_GO_X_SELF_OBSERVABILITY` to `true`.
+
+When enabled, the SDK will create the following metrics using the global `MeterProvider`:
+
+- `otel.sdk.span.live`
+- `otel.sdk.span.started`
+
+Please see the [Semantic conventions for OpenTelemetry SDK metrics] documentation for more details on these metrics.
+
+[Semantic conventions for OpenTelemetry SDK metrics]: https://github.com/open-telemetry/semantic-conventions/blob/v1.36.0/docs/otel/sdk-metrics.md
+
+## Compatibility and Stability
+
+Experimental features do not fall within the scope of the OpenTelemetry Go versioning and stability [policy](../../../../VERSIONING.md).
+These features may be removed or modified in successive version releases, including patch versions.
+
+When an experimental feature is promoted to a stable feature, a migration path will be included in the changelog entry of the release.
+There is no guarantee that any environment variable feature flags that enabled the experimental feature will be supported by the stable version.
+If they are supported, they may be accompanied with a deprecation notice stating a timeline for the removal of that support.
