-# Getting Started with Create React App

-This project was bootstrapped with [Create React App](https://github.com/facebook/create-react-app).
+This project was created with build tool [Vite](https://v2.vitejs.dev/).
+Vite (French word for "quick", pronounced /vit/, like "veet") is a build tool that aims to provide a faster and leaner development experience for modern web projects.

+## Learn More
 
-If you aren’t satisfied with the build tool and configuration choices, you can `eject` at any time. This command will remove the single build dependency from your project.
+You can learn more in the [Vite documentation: Getting Started](https://v2.vitejs.dev/guide/).
 
-Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except `eject` will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.
+To learn React, check out the [React documentation](https://reactjs.org/).
 
-You don’t have to ever use `eject`. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.
