+# UI testing
+
+This crate is just a helper crate for CI runs and development. It contains
+test code which tests the actual imag binaries and their user interfaces and
+behaviour.
+
+Tests are automatically done in temporary directories.
+The test setup removes these testing directories after tests have run.
+To prevent this, set `IMAG_UI_TEST_PERSIST`.
+
+Use the normal `RUST_LOG` functionality for logging (or see the documentation
+for the `env_logger` crate).
