-# Slint C++ Template
+# Slint & KDBindings
 
-A template for a C++ application that's using Slint for the user interface and CMake for the build system.
-
-## About
-
-This template helps you get started developing a C++ application with Slint as toolkit
-for the user interface. It demonstrates the integration between the `.slint` UI markup and
-C++ code, how to trigger react to callbacks, get and set properties and use basic widgets.
-
-## Prerequisites
-
-In order to use this template and build a C++ application, you need to install a few tools:
-
-  * **[cmake](https://cmake.org/download/)** (3.19 or newer)
-  * A C++ compiler that supports C++ version 17 or newer
-
-If your target environment is Linux or Windows on an x86-64 architecture, then you may also opt into downloading one of our binary Slint packages. These are pre-compiled and require no further tools. You can find setup instructions and download links at
-
-<https://slint-ui.com/docs/cpp/cmake.html#binary-packages>
-
-Alternatively, this template will automatically download the Slint sources and compile them. This option requires you to install Rust by following the [Rust Getting Started Guide](https://www.rust-lang.org/learn/get-started). Once this is done, you should have the ```rustc``` compiler and the ```cargo``` build system installed in your path.
-
-## Usage
-
-1. Clone or download this repository
-    ```
-    git clone https://github.com/slint-ui/slint-cpp-template my-project
-    cd my-project
-    ```
-2. Configure with CMake
-   ```
-   mkdir build
-   cmake -B build
-   ```
-3. Build with CMake
-   ```
-   cmake --build build
-   ```
-4. Run the application binary
-    * Linux/macOS:
-        ```
-        ./build/my_application
-        ```
-    * Windows:
-        ```
-        build\my_application.exe
-        ```
-
-We recommend using an IDE for development, along with our [LSP-based IDE integration for `.slint` files](https://github.com/slint-ui/slint/blob/master/tools/lsp/README.md). You can also load this project directly in [Visual Studio Code](https://code.visualstudio.com) and install our [Slint extension](https://marketplace.visualstudio.com/items?itemName=Slint.slint).
-
-## Next Steps
-
-We hope that this template helps you get started and you enjoy exploring making user interfaces with Slint. To learn more
-about the Slint APIs and the `.slint` markup language check out our [online documentation](https://slint-ui.com/docs/cpp/).
+This example explores the combination of the Slint UI toolkit with KDBindings. It leverages Slint's C++ API to create a simple backend, adapt part of it as a C++ model for use with a Slint listview and keeps things in sync using bindings and properties from KDBindings.
