 # jFxKasse
-easy payment system for small to middel sized events with a sales slip printer

-Simples Kassensystem für kleine bis mittlere Veranstalltungen bit Bon-Drucker
+Simple POS (Point of Sale) system for small to medium-sized events with receipt printer support.
+
+## Requirements
+
+- Java JDK 17+
+- Maven 3.6+
+- Display >= 1366x768
+
+## Video Tutorials (German | Deutsch)
+[YouTube Video: jFxKasse - Kassensystem - Kurzanleitung](https://www.youtube.com/watch?v=DV9DDESw40I)
+
+[YouTube Video: jFxKasse - Kassensystem - Installieren](https://www.youtube.com/watch?v=IY1bqRjwh0Q)
+
+## Setup (VSCode on openSUSE Tumbleweed)
+
+### 1. Install dependencies
+
+```bash
+sudo zypper install java-17-openjdk-devel maven
+```
+
+### 2. Install VSCode extensions
+
+Open the project in VSCode. You will be prompted to install the recommended extensions:
+
+- **Extension Pack for Java** (`vscjava.vscode-java-pack`)
+- **Maven for Java** (`vscjava.vscode-maven`)
+- **Language Support for Java** (`redhat.java`)
+
+### 3. Build & Run
+
+```bash
+# Compile
+mvn compile
+
+# Run via Maven
+mvn javafx:run
+
+# Package as fat JAR
+mvn package
+java -jar target/jFxKasse-shaded.jar
+```
+
+Or use the preconfigured VSCode tasks (`Ctrl+Shift+B`) and launch configurations (`F5`).
