+This file exports a configuration for SolidStart, [Vinxi](https://vinxi.vercel.app/), [Vite](https://vitejs.dev) and [Nitro](https://nitro.build/).
 The easiest way to generate a configuration is to use the [`defineConfig`](/solid-start/reference/config/define-config) helper.
 
 Here [`defineConfig`](/solid-start/reference/config/define-config) is used to create a minimal configuration with default settings.
