 #### Why This Error Occurred
 
-The domain you supplied cannot be verified using either the intended set of nameservers or the given verification TXT record.

-#### Possible Ways to Fix It
+#### Possible Way to Fix It
 
-Apply the intended set of nameservers to your domain or add the given TXT verification record through your domain provider.
+Apply the intended set of nameservers to your domain.
 
 You can retrieve both the intended nameservers and TXT verification record for the domain you wish to verify by running `vercel domains inspect <domain>`.
 
-When you have added either verification method to your domain, you can run `vercel domains verify <domain>` again to complete verification for your domain.
-
 Vercel will also automatically check periodically that your domain has been verified and automatically mark it as such if we detect either verification method on the domain.
 
 If you would not like to verify your domain, you can remove it from your account using `vercel domains rm <domain>`.

+# RedwoodJS Example
+
+This directory is a brief example of a [RedwoodJS](https://redwoodjs.com) app with [Serverless Functions](https://vercel.com/docs/v2/serverless-functions/introduction) that can be deployed with Vercel and zero configuration.
+
+## Deploy Your Own
+
+Deploy your own RedwoodJS project, along with Serverless Functions, with Vercel.
+
+[![Deploy with Vercel](https://vercel.com/button)](https://vercel.com/import/project?template=https://github.com/vercel/vercel/tree/master/examples/redwoodjs)
+
+_Live Example: https://redwoodjs.now-examples.now.sh_
+
+### How We Created This Example
+
+To get started with RedwoodJS on Vercel, you can [use Yarn to initialize](https://redwoodjs.com/tutorial/installation-starting-development) the project:
+
+```shell
+$ yarn create redwood-app ./my-redwood-app
+```
+
+### Deploying From Your Terminal
+
+You can deploy your new RedwoodJS project, along with [Serverless Functions](https://vercel.com/docs/v2/serverless-functions/introduction), with a single command from your terminal using [Vercel CLI](https://vercel.com/download):
+
+```shell
+$ vercel
+```

+# Static Assets
+Use this folder to add static files directly to your app. All included files and folders will be copied directly into the `/dist` folder (created when Webpack builds for production). They will also be available during development when you run `yarn rw dev`.
+>Note: files will *not* hot reload while the development server is running. You'll need to manually stop/start to access file changes.
+
+### Example Use
+A file like `favicon.png` will be copied to `/dist/favicon.png`. A folder containing a file such as `static-files/my-logo.jpg` will be copied to `/dist/static-files/my-logo.jpg`. These can be referenced in your code directly without any special handling, e.g.
+```
+<link rel="icon" type="image/png" href="/favicon.png" />
+```
+and
+```
+<img src="/static-files/my-logo.jpg"> alt="Logo" />
+```
+
+Behind the scenes, we are using Webpack's ["copy-webpack-plugin"](https://github.com/webpack-contrib/copy-webpack-plugin).
+
+## Best Practices
+Because assets in this folder are bypassing the javascript module system, **this folder should be used sparingly** for assets such as favicons, robots.txt, manifests, libraries incompatible with Webpack, etc.
+
+In general, it's best to import files directly into a template, page, or component. This allows Webpack to include that file in the bundle, which ensures Webpack will correctly process and move assets into the distribution folder, providing error checks and correct paths along the way.
+
+### Example Asset Import with Webpack
+Instead of handling our logo image as a static file per the example above, we can do the following:
+```
+import React from "react"
+import logo from "./my-logo.jpg"
+
+
+function Header() {
+  return <img src={logo} alt="Logo" />
+}
+
+export default Header
+```
+
+Behind the scenes, we are using Webpack's ["file-loader"](https://webpack.js.org/loaders/file-loader/) and ["url-loader](https://webpack.js.org/loaders/url-loader/) (for files smaller than 10kb).
