+# Bing Wallpaper Downloader
+
+Ce projet est une application Rust permettant de télécharger le wallpaper Bing du jour en Ultra HD :
+
+- `src/main.rs` : Ce fichier est le point d'entrée de l'application Rust. Il contient le code principal de l'application.
+
+- `src/data.rs` : Ce fichier contient les structures de données utiles à l'extraction de l'url de téléchargement du wallpaper.
+
+- `Cargo.toml` : Ce fichier est le fichier de configuration de Cargo, le gestionnaire de paquets et de construction de Rust. Il spécifie les dépendances du projet et les paramètres de construction.
+
+## Installation
+
+Pour installer et exécuter cette application, vous devez avoir Rust et Cargo installés sur votre système. Vous pouvez les installer en suivant les instructions sur le site officiel de Rust (https://www.rust-lang.org/).
+
+Une fois que vous avez installé Rust et Cargo, vous pouvez vous rendre dans le répertoire du projet et exécuter la commande suivante pour construire et exécuter l'application :
+
+```
+cargo run
+```
