-## Intended Usage
+The `grafana/otel-lgtm` Docker image is an open source backend for OpenTelemetry that’s intended for development, demo, and testing environments. If you are looking for a production-ready, out-of-the box solution to monitor applications and minimize MTTR (mean time to resolution) with OpenTelemetry and Prometheus, you should try [Grafana Cloud Application Observability](https://grafana.com/products/cloud/application-observability/).
 
-The intended usage is:
+## Documentation
 
-* Quick way to try OSS Grafana with OpenTelemetry.
-* Demos, presentations.
-* Integration tests for OpenTelemetry instrumentation: Run automated queries against the databases to check if expected metrics/traces/logs are present.
