 ## Community Templates
 
 create-vite is a tool to quickly start a project from a basic template for popular frameworks. Check out Awesome Vite for [community maintained templates](https://github.com/vitejs/awesome-vite#templates) that include other tools or target different frameworks. You can use a tool like [degit](https://github.com/Rich-Harris/degit) to scaffold your project with one of the templates.
