+# EV Wiki
+The EV Wiki project is a website for searching, finding and comparison of ev vehicles. 
+It works like a search engine and aggregates the data from the database to show the user the requested information in a tile based view.
+
+## Structue
+The project is structured in domain driven design manner. Inside the src-Folder, you find:
+- Application (Controllers, Commands and other symfony related application stuff)
+- Domain: The core business logic of the project. This is 100% framework agnostic code
+- Infrastructure: Implementations of Interfaces provided by the Domain layer. 
+
+The dependency is going from Application -> Domain -> Infrastrcture, but not in the opposite direction. 
+The Domain does not know about the existence of the application folder, and also the infrastructure doesn't know anything about the Domain and Application folder.
+
+## Concepts
+### Tile based results
+One core concept of the search results in the ev wiki project is the tile based search result. 
+The Tile Classes e.g. are holding view data for specific tile types. These tiles are displayed by custom twig template, one template for one tile type.
+The Tiles were aggregated and built by the Engine class that is responsible for building the tile view. 
+
+### Project dependencies
+We will barely use external dependencies. Some depencies are explicitly avoided:
+- No ORM: The project follows the philosophy, that orms destroy the needed abstraction between model (Domain) and database layer (Infrastrcture).
+          Since SQL is already a human readable language, there is no need to introduce heavy coupling between the model and the database layer.

 This application follows clean architecture principles:
 
 ### Domain Layer
-- **Documents**: MongoDB document models (`Brand`, `CarModel`, `CarRevision`)
+- **Models**: Core domain models (`Brand`, `CarModel`, `CarRevision`)
 - **Repositories**: Data access interfaces
 
 ### Application Layer
-- **Services**: Business logic (`CarSearchService`)
+- **Controllers**: HTTP request handlers
 - **Commands**: Console commands for data management
 
 ### Infrastructure Layer
-- **Controllers**: HTTP request handlers
+- **PostgreSQL**: Database implementation with native PDO
 - **Templates**: Twig templates for rendering
 
 ### Key Design Principles
 
 1. **SOLID Principles**: Each class has a single responsibility
 2. **Dependency Injection**: All dependencies are injected via constructor
-3. **No Else Statements**: Code uses early returns for better readability
-4. **Readable Names**: Self-documenting code with descriptive names
+3. **Clean Architecture**: Domain logic is independent of infrastructure
+4. **Readable Code**: Self-documenting code with descriptive names
 
-## Development
+## Database Commands
 
-### Adding New Data
-
-Use the seed command to populate the database:
+### Initialize Database
+Initialize the database with schema and sample data:
 ```bash
-php bin/console app:seed-data
+php bin/console app:database:init
 ```
 
 ### Console Commands
-
 List all available commands:
 ```bash
 php bin/console list
 ```
 
-### Database Operations
+## Database Schema
 
-The application uses MongoDB with Doctrine ODM. All database operations are handled through repositories following the Repository pattern.
+The application uses PostgreSQL with the following main tables:
+
+- **brands**: Electric vehicle manufacturers
+- **car_models**: Vehicle models belonging to brands
+- **car_revisions**: Specific revisions of car models with detailed specifications
+
+All database operations are handled through repositories following the Repository pattern, using native PDO for optimal performance.
 
 ## Styling Guidelines
 
 - **No External CSS Frameworks**: Pure CSS following modern standards
-- **Responsive Design**: Mobile-first approach
-- **Modern UI**: Clean, minimalist design inspired by search engines
-- **Accessibility**: Semantic HTML and proper contrast ratios
+- **Mobile-First**: Responsive design approach
+- **Clean Design**: Minimalist interface focusing on content
+
+## Environment Variables
+
+Required environment variables:
+
+- `APP_ENV`: Application environment (dev/prod)
+- `APP_SECRET`: Secret key for Symfony
+- `DATABASE_DSN`: PostgreSQL DSN connection string
+- `DATABASE_USER`: PostgreSQL username  
+- `DATABASE_PASSWORD`: PostgreSQL password
