+- [Remix Docs](https://remix.run/docs)
+
+## Vercel Setup
+
+First you'll need the [Vercel CLI](https://vercel.com/docs/cli):
+
+```sh
+npm i -g vercel
+```
+
+Before you can run the app in development, you need to link this project to a new Vercel project on your account.
+
+**It is important that you use a new project. If you try to link this project to an existing project (like a Next.js site) you will have problems.**
+
+```sh
+$ vercel link
+```
+
+Follow the prompts, and when it's done you should be able to get started.
+
+## Development
+
+You will be running two processes during development when using Vercel as your server.
+
+- Your Vercel server in one
+- The Remix development server in another
+
+```sh
+# in one tab
+$ vercel dev
+
+# in another
+$ npm run dev
+```
+
+Open up [http://localhost:3000](http://localhost:3000) and you should be ready to go!
+
+If you'd rather run everything in a single tab, you can look at [concurrently](https://npm.im/concurrently) or similar tools to run both processes in one tab.
+
+## Deploying
+
+```sh
+$ npm run build
+# preview deployment
+$ vercel
+
+# production deployment
+$ vercel --prod
+```
+
+### GitHub Automatic Deployments
+
+For some reason the GitHub integration doesn't deploy the public folder. We're working with Vercel to figure this out.
+
+For now, [you can set up a GitHub action with this config](https://gist.github.com/mcansh/91f8effda798b41bb373351fad217070) from our friend [@mcansh](https://github.com/mcansh).

+        When you name a route segment with $ like{" "}

+      </p>
+      <h2>Errors</h2>
+      <p>
+        When a route throws and error in it's action, loader, or component,
+        Remix automatically catches it, won't even try to render the component,
+        but it will render the route's ErrorBoundary instead. If the route
+        doesn't have one, it will bubble up to the routes above it until it hits
+        the root.
+      </p>

+        Loaders and Actions can throw a <code>Response</code> instead of an

+        This is great when loading data from a database isn't found. As soon as
