+# Experimental Features
+
+The SDK contains features that have not yet stabilized in the OpenTelemetry specification.
+These features are added to the OpenTelemetry Go 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
+
+- [Resource](#resource)
+
+### Resource
+
+[OpenTelemetry resource semantic conventions] include many attribute definitions that are defined as experimental.
+To have experimental semantic conventions be added by [resource detectors] set the `OTEL_GO_X_RESOURCE` environment variable.
+The value set must be the case-insensitive string of `"true"` to enable the feature.
+All other values are ignored.
+
+<!-- TODO: document what attributes are added by which detector -->
+
+[OpenTelemetry resource semantic conventions]: https://opentelemetry.io/docs/specs/semconv/resource/
+[resource detectors]: https://pkg.go.dev/go.opentelemetry.io/otel/sdk/resource#Detector
+
+#### Examples
+
+Enable experimental resource semantic conventions.
+
+```console
+export OTEL_GO_X_RESOURCE=true
+```
+
+Disable experimental resource semantic conventions.
+
+```console
+unset OTEL_GO_X_RESOURCE
+```
+
+## 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.
