+# Welcome to Remix!
+
+- [Remix Docs](https://remix.run/docs)
+
+## Deployment
+
+After having run the `create-remix` command and selected "Vercel" as a deployment target, you only need to [import your Git repository](https://vercel.com/new) into Vercel, and it will be deployed.
+
+If you'd like to avoid using a Git repository, you can also deploy the directory by running [Vercel CLI](https://vercel.com/cli):
+
+```sh
+npm i -g vercel
+vercel
+```
+
+It is generally recommended to use a Git repository, because future commits will then automatically be deployed by Vercel, through its [Git Integration](https://vercel.com/docs/concepts/git).
+
+## Development
+
+To run your Remix app locally, make sure your project's local dependencies are installed:
+
+```sh
+npm install
+```
+
+Afterwards, start the Remix development server like so:
+
+```sh
+npm run dev
+```
+
+Open up [http://localhost:3000](http://localhost:3000) and you should be ready to go!
+
+If you're used to using the `vercel dev` command provided by [Vercel CLI](https://vercel.com/cli) instead, you can also use that, but it's not needed.

+        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
