+# OpenTelemetry Collector CRDs
+
+This chart contains the CRDs for _*installation*_ only right now for the opentelemetry-operator. This allows the Splunk OpenTelemetry Collector chart to work on install. You can see more discussion about this [here](https://github.com/open-telemetry/opentelemetry-helm-charts/issues/677) and [here](https://github.com/open-telemetry/opentelemetry-helm-charts/pull/1203).
+
+This approach is inspired by the [opentelemetry-kube-stack chart](https://github.com/open-telemetry/opentelemetry-helm-charts/tree/main/charts/opentelemetry-kube-stack) approach.
+
+> [!NOTE]
+> The splunk-otel-collector chart only supports and tests functionality related to the auto-instrumentation that requires the Instrumentation CRD.
+> Other CRDs, such as OpenTelemetryCollector and OpAMPBridge, are included solely to allow the Operator to start up and are not currently supported or tested.
+
+# Upgrade Notes
+
+Right now, upgrades are NOT handled by this chart, however that could change in the future. This is what is run to bring in the CRDs today.
