# Getting Started This tutorial uses JavaScript as the host programming language. Slint also supports other programming languages like [Rust](https://slint.dev/docs/rust/slint/) or [C++](https://slint.dev/docs/cpp/). We recommend using [our editor integrations for Slint](https://github.com/slint-ui/slint/tree/master/editors) for following this tutorial. Slint has an application template you can use to create a project with dependencies already set up that follows recommended best practices. Clone the template with the following command: ```sh git clone https://github.com/slint-ui/slint-nodejs-template memory cd memory ``` Install dependencies with npm: ```sh npm install ``` The `package.json` file references `src/main.js` as the entry point for the application and `src/main.js` references `memory.slint` as the UI file. Replace the contents of `src/main.js` with the following: ```js {{#include main_initial.js:main}} ``` The `slint.loadFile` method resolves files from the process's current working directory, so from the `package.json` file's location. Replace the contents of `ui/appwindow.slint` with the following: ```slint {{#include memory.slint:main_window}} ``` Run the example with `npm start` and a window appears with the green "Hello World" greeting.
