## Where To Start

- Updating the project index: preserve release ordering, keep it focused on project information and model links, and check desktop/mobile layouts and provider filtering without editing model pages.
- Changing a watch face: read the Model and Contributor Guide, then check the Watch Face Catalog.
- Creating or refreshing a model page: read Model Versioning, then the Model and Contributor Guide.
- Making any repository change: read GitHub Workflow.
- Preparing for a public showcase or release: read the Public Release Checklist.
