+> - **Required**: `config.yaml` file (needed for the app to run)
+>

+>    ```bash
+>    # Linux/macOS
+>    mkdir -p data plugins themes
+>    curl -O https://raw.githubusercontent.com/gamosoft/notediscovery/main/config.yaml
+>    # Download at least light and dark themes
+>    curl -o themes/light.css https://raw.githubusercontent.com/gamosoft/notediscovery/main/themes/light.css
+>    curl -o themes/dark.css https://raw.githubusercontent.com/gamosoft/notediscovery/main/themes/dark.css
+>    ```
+>    
+>    ```powershell
+>    # Windows PowerShell
+>    mkdir data, plugins, themes -Force
+>    Invoke-WebRequest -Uri https://raw.githubusercontent.com/gamosoft/notediscovery/main/config.yaml -OutFile config.yaml
+>    # Download at least light and dark themes
