+## Opentelemetry Instana Exporter Demo
+
+https://www.ibm.com/docs/en/instana-observability/243?topic=nodejs-opentelemetry-integration#serverless-opentelemetry-exporter
+
+This demo will transform Otel spans into Instana spans using the Instana exporter. The spans are send directly to the serverless acceptor in our backend. Data is generated every 5s.
+
+1. Copy env.example to .env
+2. Add APP_PORT, INSTANA_AGENT_KEY and INSTANA_ENDPOINT_URL. (You need to use the serverless endpoint)
+3. `npm run start`
+4. Go to services and look for "Instana Exporter Demo"
+
