-## What is this?
-
-This is the Vue 3.x version of [ReactToPrint](https://github.com/gregnb/react-to-print).
-
-> Thanks to the [contributors](https://github.com/gregnb/react-to-print/graphs/contributors) of `ReactToPrint` whose work made this package possible.
-
-VueToPrint aims to be as consistent as possible with ReactToPrint so that you can use the same API. However, there are some differences due to the differences between Vue 3.x and React.
