+## Testing Organization
+
+Testing is organized around what a user can do and see/not see. Test scenarios are grouped by the **user action** and the **object** of that action. This makes it easier to locate and reason about requirements.
+
+Here is a brief overview of how things fit together.
+
+```bash
+features
+└── {action}_{object}.feature   # Specify test scenarios
+tests
+├── fixtures
+│   ├── action.rs               # Perform a user action (click, type, etc.)
+│   ├── check.rs                # Assert what a user can see/not see
+│   ├── find.rs                 # Query page elements
+│   ├── mod.rs
+│   └── world
+│       ├── action_steps.rs     # Map Gherkin steps to user actions
+│       ├── check_steps.rs      # Map Gherkin steps to user expectations
+│       └── mod.rs
+└── app_suite.rs                # Test main
