-## File-based Routing
-
-Routes will be auto-generated for Vue files in this dir with the same file structure.
-Check out [`unplugin-vue-router`](https://github.com/posva/unplugin-vue-router) for more details.
-
-### Path Aliasing
-
-`@/` is aliased to `./src/` folder.
-
-For example, instead of having
-
-```ts
-import { isDark } from '../../../../composables'
-```
-
-now, you can use
-
-```ts
-import { isDark } from '@/composables'
-```
