Welcome to the [OpenTelemetry Demo](/ecosystem/demo/) documentation, which
covers how to install and run the demo, and some scenarios you can use to view
OpenTelemetry in action.

## Running the Demo

Want to deploy the demo and see it in action? Start here.

- [Docker](docker-deployment/)
- [Kubernetes](kubernetes-deployment/)

## Language Feature Reference

## Scenarios

How can you solve problems with OpenTelemetry? These scenarios walk you through
some pre-configured problems and show you how to interpret OpenTelemetry data to
solve them.

We'll be adding more scenarios over time.

- Generate a [Product Catalog error](feature-flags) for `GetProduct` requests
  with product id: `OLJCESPC7Z` using the Feature Flag service
- Discover a memory leak and diagnose it using metrics and traces.
