 3.  Run the `docker-compose up` command.
 
 Citrix ADC Observability Exporter is deployed and exposed on port 5557 and port 5563 for Citrix ADC transaction data and metrics data respectively.
 
+### Prometheus standalone deployment
+
+For Citrix ADC observability exporter, with Prometheus as the endpoint following is the `lstreamd_default.conf` file configuration.
+
+            {
+                "Endpoints": {
+                    "ZIPKIN": {

 ## Integrate Citrix ADC with multiple Citrix ADC Observability Exporter instances manually
 
 You can configure Citrix ADC Observability Exporter manually in Citrix ADC. Manual configuration is suitable for Citrix ADC in MPX and VPX form factors. We recommend deploying the Citrix ADC Observability Exporter in the automated way with the YAML file as described in the preceding sections.
