+# Slint Rust Template
+
+A template for a Rust application that's using [Slint](https://slint.rs) for the user interface.
+
+## About
+
+This template helps you get started developing a Rust application with Slint as toolkit
+for the user interface. It demonstrates the integration between the `.slint` UI markup and
+Rust code, how to trigger react to callbacks, get and set properties and use basic widgets.
+
+## Usage
+
+1. 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.
+2. Install [`cargo-generate`](https://github.com/cargo-generate/cargo-generate)
+    ```
+    cargo install cargo-generate
+    ```
+3. Set up a sample project with this template
+    ```
+    cargo generate --git https://github.com/slint-ui/slint-rust-template --name my-project
+    cd my-project
+    ```
+3. Build with cargo
+    ```
+    cargo build
+    ```
+4. Run the application binary
+     ```
+     cargo run
+     ```
+
+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.dev/docs).
+
+Don't forget to edit this README to replace it by yours
