An App Module is comprised of two primary directories.

• src/
• app/
• module/

**Note:** The `app/` directory contains the scaffolding for a lightweight app for local development and does not include files that will be integrated with the experimentation-ui app.

• views/ `- individual views usually associated with a specific route`
