-## Setup
+## CLI
 
-By default, [Vercel](https://vercel.com) will run your `build` script in the `package.json` and automatically detect the built entry point within `.vercel_build_output/`.
+1. Install the [Vercel CLI](https://vercel.com/cli).
+2. Vercel will detect that you are using Nuxt and will enable the correct settings for your deployment.
+3. Your application is deployed! (e.g. [nuxt.vercel.app](https://nuxt.vercel.app/))
 
-## Deployment
+```bash
+$ npm i -g vercel
+$ npx nuxi init -t v3-vercel
+$ vercel
 
-Just push to your git repository [as you would normally do for Vercel](https://vercel.com/docs/git).
+## Git
+
+1. Push your code to your git repository (GitHub, GitLab, BitBucket).
+2. [Import your project](https://vercel.com/new) into Vercel.
+3. Vercel will detect that you are using Nuxt and will enable the correct settings for your deployment.
+4. Your application is deployed! (e.g. [nuxt.vercel.app](https://nuxt.vercel.app/))
+
+After your project has been imported and deployed, all subsequent pushes to branches will generate [Preview Deployments](https://vercel.com/docs/concepts/deployments/environments#preview), and all changes made to the Production Branch (commonly “main”) will result in a [Production Deployment](https://vercel.com/docs/concepts/deployments/environments#production).
