What problem does it solve? Developers joining or working in the pellegrims.coach codebase need a single reference for project structure, build commands, coding conventions, and CMS architecture without digging through scattered config files. ## Core Features & Use Cases - Project Orientation: Maps the src/ directory layout, including App Router route groups (site) and (payload), collections, components, and i18n utilities. - Command Reference: Lists npm scripts for development, builds, Payload type generation, migrations, seeding, linting, and Playwright E2E tests. - Architecture Guidance: Explains the Payload CMS 3 integration with SQLite/libSQL, the dual i18n system (en, nl), and the Expand-and-Contract database migration pattern. - Use Case: A developer adding a new Payload collection uses this guide to follow naming conventions, run npm run generate:types, and create a migration safely. ## Quick Start Ask the AI to explain the project structure and the correct commands for adding a new Payload collection in this repository.
