-2. Every single oCIS service has its own environment variables for enabling and configuring tracing. You can, for example,
-enable tracing in Reva when starting the oCIS single binary like this:
-    ```console
-    REVA_TRACING_ENABLED=true \
-    REVA_TRACING_ENDPOINT=localhost:6831 \

+    1. You can enable and configure tracing on each service individually. For example, enable tracing
+        in Reva when starting the oCIS single binary like this:
+        ```console
+        REVA_TRACING_ENABLED=true \
+        REVA_TRACING_ENDPOINT=localhost:6831 \
+        REVA_TRACING_COLLECTOR=http://localhost:14268/api/traces \
+        ./bin/ocis server
+        ```
+    2. Enabling and configuring tracing on oCIS itself will forward the configuration to all services:
+        ```console
+        OCIS_TRACING_ENABLED=true \
+        OCIS_TRACING_ENDPOINT=localhost:6831 \
+        OCIS_TRACING_COLLECTOR=http://localhost:14268/api/traces \
+        ./bin/ocis server
+        ```
+       If you want to set individual tracing configuration for each service, make sure to set
+       `OCIS_TRACING_ENABLED=false`.
 3. Make the actual request that you want to trace.
 4. Open up the [Jaeger UI](http://localhost:16686) to analyze request traces.
