+# KickerELO
+
+KickerELO is a web application for displaying Elo ratings for foosball (table soccer) games.  
+It uses **Spring Boot** for the backend, **Vaadin** for the frontend, and **MariaDB** as the database.
+
+## Requirements
+
+- **Java 23** or later
+- **Maven** (if not integrated)
+- **MariaDB** (for production use)
+
+## Installation
+
+### 1️⃣  Clone the repository
+```sh
+git clone https://github.com/your-repo/kickerelo.git
+cd kickerelo
+```
+
+### 2️⃣  Set up the database
+
+- **For testing**: No database setup is required, as an H2 in-memory database is used by default.
+- **For production**: The application requires MariaDB. If MariaDB is already installed, make sure the database and
+credentials are correctly configured in `application.properties`.
+
+If you don't have MariaDB installed, you can quickly start a database using Docker:
+
+```sh
+docker run --name kickerelo-db -e MYSQL_ROOT_PASSWORT=root -e MYSQL_DATABASE=kickerelo -p 3306:3306 -d mariadb:latest
+```
+
+### 3️⃣  Build the project
+
+To generate the file `target/kickerelo.jar`:
+
+```sh
+mvn clean package
+```
+
+### 4️⃣  Run the application
+
+- For testing (default):
+
+```sh
+mvn spring-boot:run
+```
+
+- For production (requires MariaDB):
+
+```sh
+mvn spring-boot:run -Dspring-boot.run.profiles=production
+```
+
+Alternatively, you can run the built .jar file:
+
+```sh
+java -jar target/kickerelo.jar
+```
