+To use imports relative to a path you specify, and from `node_modules` without adding the `~` prefix, you can add a [`.env` file](https://github.com/facebook/create-react-app/blob/master/docusaurus/docs/adding-custom-environment-variables.md#adding-development-environment-variables-in-env) at the project root with the variable `SASS_PATH=node_modules:src`.

+If you set `SASS_PATH=node_modules:src`, this will allow you to do imports like
