+## Verifying Your Setup
+To verify everything is working correctly:
+
+1. **Check ClickHouse**: `curl http://localhost:8123/ping` (should return "Ok.")
+2. **Check OTel Collector**: `curl http://localhost:13133` (should return health status)
+3. **Check Backend**: `curl http://localhost:8080/api/v1/health` (should return `{"status":"ok"}`)
+4. **Check Frontend**: Open `http://localhost:3301` in your browser
+
+## How to send test data?
+
+You can now send telemetry data to your local SigNoz instance:
+
+- **OTLP gRPC**: `localhost:4317`
+- **OTLP HTTP**: `localhost:4318`
+
+For example, using `curl` to send a test trace:
+```bash
+curl -X POST http://localhost:4318/v1/traces \
+  -H "Content-Type: application/json" \
+  -d '{"resourceSpans":[{"resource":{"attributes":[{"key":"service.name","value":{"stringValue":"test-service"}}]},"scopeSpans":[{"spans":[{"traceId":"12345678901234567890123456789012","spanId":"1234567890123456","name":"test-span","startTimeUnixNano":"1609459200000000000","endTimeUnixNano":"1609459201000000000"}]}]}]}'
