-### Install the Helm Chart
-
-#### Installation modes
-
-This chart supports two `global.installationMode` values:
-
-- **`singleCluster`** *(default)*: Deploy the OpenTelemetry Collector into a single cluster where both the dataplane and the observability plane reside.
-- **`multiClusterReceiver`**: Deploy the OpenTelemetry Collector as a central receiver in the observability plane cluster. It accepts OTLP traces from remote dataplane clusters and forwards them to Moesif.
-
-#### Single-cluster topology
-
-```bash
-helm upgrade --install observability-tracing-moesif \
-  oci://ghcr.io/openchoreo/helm-charts/observability-tracing-moesif \
-  --create-namespace \
-  --namespace openchoreo-observability-plane \
-  --version 0.1.0
-```
-
-#### Multi-cluster topology (receiver)
-
-Install in the observability plane cluster. An HTTPRoute will be created so that dataplane clusters can push OTLP traces over HTTP/gRPC.
-
-```bash
-helm upgrade --install observability-tracing-moesif \
-  oci://ghcr.io/openchoreo/helm-charts/observability-tracing-moesif \
-  --create-namespace \
-  --namespace openchoreo-observability-plane \
-  --version 0.1.0 \
-  --set global.installationMode="multiClusterReceiver"
-```
-
 ### Configuration Options
 
 For easier configuration management, create a `moesif-tracing-values.yaml` file:
 
 ```yaml
 # moesif-tracing-values.yaml
 
-global:
-  # installationMode: "singleCluster"   # default
-  # installationMode: "multiClusterReceiver"
-
 moesif:
   # List of environment names to collect traces from.
   # These must match the openchoreo.dev/environment label on your resources.

 3. Routes traces to the correct Moesif application based on the `openchoreo.dev/environment` resource attribute.
 4. Exports traces to Moesif using the Moesif Collector Application ID stored in the `moesif-tracing-secret` Kubernetes secret.
