 # Developing, Testing, and Contributing
 
-Detailed information regarding development and testing environments setup and configuration can be found [here](https://github.com/samvera-labs/iiif_print/wiki/Installing,-Developing,-and-Testing)
+We develop the IIIF Print gem using Docker and Docker Compose.  You'll want to clone this repository and run the following commands:
 
-A Vagrant VM is available for users and developers to quickly and easily deploy the latest IiifPrint codebase using Vagrant and VirtualBox. See [samvera-newspapers-vagrant](https://github.com/samvera-labs/samvera-newspapers-vagrant) for more.
+```shell
+$ docker compose build
+$ docker compose up
+$ docker compose exec web bash
+```
 
-Additionally, the [IiifPrint Demo Site](https://newspaperworks.digitalnewspapers.org/) is available for those interested in testing out IiifPrint as deployed in a vanilla Hyrax application. (**NOTE:** The demo site may not be running the latest release of IiifPrint.)
+You'll now be inside the web container:
+
+```shell
+$ bundle exec rake
+```
+
+The above will build the test application (if it doesn't already exist).  During the rebuild you might get a notice on a conflict for files.  It will ask you to override.  We recommend that you select the "accept all" option (e.g. Typing <kbd>a</kbd>).
+
+To rebuild the test application, delete the `.internal_test_app` directory.
