-## Structure
+## Project Structure
 
-- **Unity/** - Unity VR/AR application with educational tasks
-  - `Assets/Scenes/VR/` - VR learning tasks (1-4, task 1 currently usable)
-  - `Assets/Scenes/AR/` - AR learning tasks (1-4, task 1 currently usable)
-  - Uses Convai SDK for AI-powered conversations and Ready Player Me avatars
-  - `TaskTimer.cs` - Manages a configurable countdown timer for tasks (e.g., duration, warning threshold, auto-start), displaying time in UI and changing color when time is low. Automatically loads the "Lobby" scene upon expiration.
-  - `TaskButtonManager.cs` - Facilitates scene navigation, allowing users to switch between VR/AR tasks (1-4) using number keys (1-8) and return to the "Lobby" scene using 'L' or '0'.
-  - `PositionTracker.cs` - Records and saves the positions of two specified Unity `Transform` objects to a CSV file at a configurable interval, useful for data collection.
+### Unity VR/AR Application (`Unity/`)
 
-- **Chat-App/** - Flutter-based AI Chat Lab application
-  - Cross-platform chat interface (Android, iOS, Windows, Linux, macOS, Web)
-  - Connects to AI backend for conversational learning
-  - Uses Convai SDK for AI-powered conversations
-  - Stores conversations with possibility to automatically translate using DeepL API
+#### Scenes

+- Meta Quest (Oculus) XR support
+
+#### Setup Instructions
+
+1. **Enable Quest Link**
+   - Open the Oculus app on your PC
+   - Connect your Quest headset via USB-C cable
+   - Put on your headset and enable Quest Link when prompted
+   - Alternatively, use Air Link for wireless connection (Settings → Experimental)
+
+2. **Enable Beta Passthrough (for AR tasks)**
+   - On your PC, open the Oculus app
+   - Go to **Settings → Beta**
+   - Enable **"Passthrough over Oculus Link"** or **"Passthrough API"**
+   - Restart the Oculus app and reconnect your headset
+
+3. **Run the Unity Project**

+
+#### Development
+To develop or run the application from source, you'll need to set up your Flutter development environment.
+
+1.  **Install Flutter SDK**
+    *   Follow the official Flutter installation guide for your operating system: [https://flutter.dev/docs/get-started/install](https://flutter.dev/docs/get-started/install)
+    *   Ensure you have all necessary dependencies (e.g., Android Studio, Xcode for iOS, VS Code, etc.) and run `flutter doctor` to verify your setup.
+
+2.  **Run the Application**
+    *   Navigate to the `Chat-App/` directory in your terminal:
+        ```bash
+        cd Chat-App/
+        ```
+    *   Get the project dependencies:
+        ```bash
+        flutter pub get
+        ```
+    *   Run the application on your desired platform (e.g., Android, Windows, Web):
+        ```bash
+        flutter run
+        ```
+        *   To run on a specific device or platform, use the `-d` flag (e.g., `flutter run -d windows`, `flutter run -d chrome`, `flutter run -d <device_id>`).
+        *   Ensure you have a device connected or an emulator/simulator running for mobile platforms.
