 Our goal is to provide a practical, reusable reference environment for applications.  The first step is providing an on-ramp for Hyrax engine development. Then providing help with Hyrax-based application development. Finally, providing better guidance around deployment.
 
 The [Hyrax Engine Development](#hyrax-engine-development) is further along than the [Docker Image for Hyrax-based Applications](#docker-image-for-hyrax-based-applications) which is further along than [Deploying to Production](#deploying-to-production).

+There are two options for development environments to run:
 
 - [Dassie](#dassie-internal-test-app-with-activefedora) is the default internal test app that will run an ActiveFedora-based Hyrax web application using Fedora 4 as the backend storage. See [Troubleshooting Dassie](#troubleshooting-dassie) if you encounter any issues.
 - [Koppie](#koppie-internal-test-app-with-valkyrie-connector-to-postgres) is a newer internal test app that is a Valkyrie-based Hyrax web application that runs with PostGres as backend storage. It does not run ActiveFedora or use Fedora 4. See [Troubleshooting Koppie](#troubleshooting-koppie) if you encounter any issues.

 We support a `docker-compose`-based development environment for folks working on
 the Hyrax engine. This environment is substantially more like a Hyrax production
 setup than the older `fedora_wrapper`/`solr_wrapper` approach.

 the [Samvera organization][samvera-packages].  To build them:
