# Setting up for yarn workspaces
> Configure React Email on a yarn monorepo
This is a guide intended at users of [yarn modern](https://yarnpkg.com/getting-started/qa#why-should-you-upgrade-to-yarn-modern).
For those who are using [yarn classic](https://www.npmjs.com/package/yarn) (`1.x`), you can do something similar to the
[pnpm guide](/getting-started/monorepo-setup/pnpm).
## 1. Create transactional workspace
Create a new folder called `transactional` inside of where you keep workspace packages (generally `./packages/*`).
Include a new `package.json` and do not forget to add this to the `workspaces` of your monorepo's `package.json`.

## 2. Set linker either to `node-modules` or to `pnpm`
Currently, React Email can only work with yarn's `node-modules` and `pnpm` [install modes](https://yarnpkg.com/features/linkers)
so you will need to set it to one of these two on your `.yarnrc.yml` file:
```yml .yarnrc.yml theme={"theme":{"light":"github-light","dark":"vesper"}}
nodeLinker: node-modules
```
## 3. Install dependencies
Install React Email in the `transactional` workspace.
```sh packages/transactional theme={"theme":{"light":"github-light","dark":"vesper"}}
yarn add @react-email/ui -D -E
yarn add react-email react react-dom -E
```
## 4. Add scripts
Include the following script in your `package.json` file.
```json packages/transactional/package.json theme={"theme":{"light":"github-light","dark":"vesper"}}
{
// ...
"scripts": {
"dev": "email dev"
}
// ...
}
```
## 5. Write your emails
Create a new folder called `emails`, create a file inside called `email.tsx` and add the following example code:
```jsx packages/transactional/emails/email.tsx theme={"theme":{"light":"github-light","dark":"vesper"}}
import { Button, Html, Head, Body } from "react-email";
import * as React from "react";
export default function Email() {
return (
