+# Project Guidelines for Junie
+
+## Project Overview
+
+Chill is a comprehensive web application built as a set of Symfony bundles. It is a case management system, for social work. The project consists of multiple specialized bundles that provide different functionalities:
+
+- **ChillMainBundle**: Core bundles that provide the foundation of the application
+- **ChillPersonBundle**: Core bundles that provide the foundation of the bundles associated to person (which is the case for all other bundles)
+- **ChillCalendarBundle**: Calendar and scheduling functionality
+- **ChillDocStoreBundle** and **ChillDocGeneratorBundle**: Document management and generation
+- **ChillActivityBundle**, **ChillEventBundle**, **ChillTaskBundle**: Activity and task tracking
+- **ChillBudgetBundle**: Financial management
+- **ChillThirdPartyBundle**: Integration with external systems
+- **ChillCustomFieldsBundle**: Extensibility through custom fields
+- **ChillReportBundle**: Reporting capabilities
+- And several other specialized bundles
+
+## Technology Stack
+
+- **Backend**: PHP 8.3+, Symfony 5.4
+- **Frontend**: JavaScript/TypeScript, Vue.js 3, Bootstrap 5
+- **Build Tools**: Webpack Encore, Yarn
+- **Database**: PostgreSQL with materialized views
+- **Other Services**: Redis, AMQP (RabbitMQ), SMTP
+
+## Project Structure
+
+Note: This is a project which exists from a long time ago, and we found multiple structure inside each bundle. When having the choice, the developers should choose the new structure.
+
+The project follows a standard Symfony bundle structure:
+- `/src/Bundle/`: Contains all the Chill bundles. The code is either at the root of the bundle directory, or within a `src/` directory (preferred). See psr4 mapping at the root's `composer.json`.
+- each bundle come with his own tests, either in the `Tests` directory (when the code is directly within the bundle directory (for instance `src/Bundle/ChillMainBundle/Tests`, `src/Bundle/ChillPersonBundle/Tests`)), or inside the `tests` directory, alongside to the `src/` sub-directory (example: `src/Bundle/ChillWopiBundle/tests`) (this is the preferred way).
+- `/docs/`: Contains project documentation
+
+Each bundle typically has the following structure:
+
+- `Controller/`: Contains controllers
+- `Entity/`: Contains Doctrine entities
+- `Repository/`: Contains Doctrine repositories
+- `Resources/`: Contains views, translations, and public assets
+- `DependencyInjection/`: Contains service configuration
+- `Export/`: Contains services related to exports
+- `Security/`: Contains services related to security. Most of the time, those are new voters, and so on.
+
+## Development Guidelines
+
+### Building the Project
+
+Before submitting any changes, you should build the project to ensure that all assets are properly compiled:
+
+```bash
+yarn run encore production
+```
+
+For development with hot-reloading:
+
+```bash
+yarn run encore dev --watch
+```
+
+### Testing
+
+The project uses PHPUnit for testing. Each bundle has its own test suite, and there's also a global test suite at the root level. When making changes, you should run the relevant tests to ensure that your changes don't break existing functionality.
+
+The tests are run globally, but each bundle is within a test suite.
+
+```bash
+# to run test for a bundle "Name":
+vendor/bin/phpunit --testsuite NameBundle
+```
+
+### Code Style
+
+The project uses ESLint for JavaScript/TypeScript code quality. You can run the linter with:
+
+```bash
+yarn run eslint
+```
+
+For PHP, we use three tools:
+
+- php-cs-fixer, that we can run using globally installed php-cs-fixer command;
+- phpstan, that we can run using `vendor/bin/phpstan`. We use level phpstan level 5.
+- rector, that we can run using `vendor/bin/rector`.
+
+## Deployment
+
+The project can be deployed in a production environment following Symfony's deployment guidelines. The documentation provides detailed instructions for setting up a production environment.
+
+## Documentation
+
+Comprehensive documentation is available in the `/docs/` directory, including installation instructions, configuration guides, and operational procedures.
+
+## Conclusion
+
+When working with this project, Junie should:
+
+1. Understand the modular bundle structure and how the different components interact
+2. Build the project before submitting changes to ensure assets are properly compiled
+3. Run relevant tests to ensure changes don't break existing functionality
+4. Follow the established code style and patterns
