 ### Vercel
 
-This example uses the latest Vercel platform version 2.
+[Vercel](https://vercel.com/home) is a cloud platform that enables developers to host Jamstack websites and web services that deploy instantly, scale automatically, and requires no supervision, all with zero configuration. They provide a global edge network, SSL encryption, asset compression, cache invalidation, and more.
 
-1. Install the Vercel CLI:
+#### Step 1: Deploying your Vue project to Vercel
 
-```bash
-npm install -g vercel
+To deploy your Vue project with a [Vercel for Git Integration](https://vercel.com/docs/git-integrations), make sure it has been pushed to a Git repository.
 
-# Or, if you prefer a local one
-npm install vercel
-```
+Import the project into Vercel using the [Import Flow](https://vercel.com/import/git). During the import, you will find all relevant [options](https://vercel.com/docs/build-step#build-&-development-settings) preconfigured for you with the ability to change as needed.
 
-2. Add a `vercel.json` file to your project root:
+After your project has been imported, all subsequent pushes to branches will generate [Preview Deployments](https://vercel.com/docs/platform/deployments#preview), and all changes made to the [Production Branch](https://vercel.com/docs/git-integrations#production-branch) (commonly "master" or "main") will result in a [Production Deployment](https://vercel.com/docs/platform/deployments#production).
 
-    ```json
-    {
-      "name": "my-example-app",
-      "version": 2,
-      "builds": [
-        {
-          "src": "package.json",
-          "use": "@vercel/static-build"
-        }
-      ],
-      "routes": [
-        {
-          "src": "/(js|css|img)/.*",
-          "headers": { "cache-control": "max-age=31536000, immutable" }
-        },
-        { "handle": "filesystem" },
-        { "src": ".*", "dest": "/" }
-      ],
-      "alias": "example.com"
-    }
-    ```
+Once deployed, you will get a URL to see your app live, such as the following: https://vue-example-tawny.vercel.app/.
 
-    If you have different/additional folders, modify the route accordingly:
-
-    ```diff
-    - {
-    -   "src": "/(js|css|img)/.*",
-    -   "headers": { "cache-control": "max-age=31536000, immutable" }
-    - }
-    + {
-    +   "src": "/(js|css|img|fonts|media)/.*",
-    +   "headers": { "cache-control": "max-age=31536000, immutable" }
-    + }
-    ```
+#### Step 2 (optional): Using a Custom Domain
 
-    If your `outputDir` is not the default `dist`, say `build`:
-
-    ```diff
-    - {
-    -   "src": "package.json",
-    -   "use": "@vercel/static-build"
-    - }
-    + {
-    +   "src": "package.json",
-    +   "use": "@vercel/static-build",
-    +   "config": { "distDir": "build" }
-    + }
-    ```
+If you want to use a Custom Domain with your Vercel deployment, you can **Add** or **Transfer in** your domain via your Vercel [account Domain settings.](https://vercel.com/dashboard/domains)
 
-3. Adding a `now-build` script in `package.json`:
+To add your domain to your project, navigate to your [Project](https://vercel.com/docs/platform/projects) from the Vercel Dashboard. Once you have selected your project, click on the "Settings" tab, then select the **Domains** menu item. From your projects **Domain** page, enter the domain you wish to add to your project.
 
-    ```json
-    "vercel-build": "npm run build"
-    ```
+Once the domain as been added, you will be presented with different methods for configuring it.
+
+#### Deploying a fresh Vue project
+
+You can deploy a fresh Vue project, with a Git repository set up for you, with the following Deploy Button:
+
+[![Deploy with Vercel](https://vercel.com/button)](https://vercel.com/import/git?s=https%3A%2F%2Fgithub.com%2Fvercel%2Fvercel%2Ftree%2Fmaster%2Fexamples%2Fvue)
 
-    To make a deployment, run `vercel`.
+## References:
 
-    If you want your deployment aliased, run `vercel --target production` instead.
