+## integration tests
+
+### `tcli`
+
+Package `tcli` provides a framework for writing end-to-end CLI tests.
+Each test group can have its own container for executing commands in a consistent
+and isolated filesystem.
+
+### prerequisites
+
+Assign the following environment variables to run the integration tests
+against an existing Enterprise deployment instance.
+
+```bash
+export CODER_URL=...
+export CODER_EMAIL=...
+export CODER_PASSWORD=...
+```
+
+Then, simply run the test command from the project root
+
+```sh
+go test -v ./ci/integration
+```
