+## Tests
+
+To run basic integration tests using Docker:
+
+  1. [Install Docker](https://docs.docker.com/engine/installation/).
+  2. In this project directory, run: `composer run-tests`
+
+> Note: If you're on a Mac, and want to use Docker's `cached` volume option (or `delegated`, once it's available) for faster local filesystem access, you need to install [Docker's Edge release](https://docs.docker.com/docker-for-mac/install/#download-docker-for-mac).
+
+The project's automated tests are run via Travis CI, and the more comprehensive test suite covers multiple Linux distributions and many different Drupal VM use cases and deployment techniques.
