### [Read this on the main serverless docs site](https://www.serverless.com/framework/docs/providers/cloudflare/guide/installation) # Cloudflare Workers - Installation ## Installing Cloudflare Workers Cloudflare Workers don’t actually require any installation to run. However, You will need to set your Global API key from Cloudflare as an environmental variable named `CLOUDFLARE_AUTH_KEY`, and your Cloudflare account email as an environmental variable named `CLOUDFLARE_AUTH_EMAIL`. You can get your Global API key from your [Cloudflare profile](https://dash.cloudflare.com/profile) page. Environmental variables are variables that live inside your terminal. For Mac and Linux users, you can set environmental variables like this: ```bash export CLOUDFLARE_AUTH_KEY=YOUR_API_KEY_HERE export CLOUDFLARE_AUTH_EMAIL=YOUR_CLOUDFLARE_EMAIL ``` And for Windows (CMD) users, you can set environmental variables like this: ```bash set CLOUDFLARE_AUTH_KEY=YOUR_API_KEY_HERE set CLOUDFLARE_AUTH_EMAIL=YOUR_CLOUDFLARE_EMAIL ``` You’ll need to redefine your environmental variables after each time you close your terminal. ## Installing the Serverless Framework Next, install the Serverless Framework via [npm](https://npmjs.org) which was already installed when you installed Node.js. Open up a terminal and type `npm install -g serverless` to install Serverless. ```bash npm install -g serverless ``` Once the installation process is done you can verify that Serverless is installed successfully by running the following command in your terminal: ```bash serverless ``` To see which version of serverless you have installed run: ```bash serverless --version ``` Remember, you need at least version 1.31.0 to use Cloudflare Workers with Serverless. ## Installing the serverless-cloudflare-workers plugin Finally, add our `serverless-cloudflare-workers` plugin to your project by running `npm install --save serverless-cloudflare-workers`.
