+
+#### Why This Error Occurred
+
+You attempted to create a Vercel deployment where the input is a file, rather than a directory. Previously this was allowed, however this behavior has been removed as of Vercel CLI v24.0.0 because it exposed a potential security risk if the user accidentally created a deployment from a sensitive file.
+
+#### Possible Ways to Fix It
+
+- Run the `vercel deploy` command against a directory, instead of a file.

+# 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.

+# SolidStart
+
+Everything you need to build a Solid project, powered by [`solid-start`](https://github.com/ryansolid/solid-start/tree/main/packages/start);
+
+## Deploy Your Own
+
+[![Deploy with Vercel](https://vercel.com/button)](https://vercel.com/new/clone?repository-url=https://github.com/vercel/vercel/tree/main/examples/solidstart&template=solidstart)
+
+## Developing
+
+Once you've created a project and installed dependencies with `npm install` (or `pnpm install` or `yarn`), start a development server:
+
+```bash
+npm run dev
+
+# or start the server and open the app in a new browser tab
+npm run dev -- --open
+```
+
+## Building
+
+This uses the [Vercel Adapter](https://github.com/solidjs/solid-start/tree/main/packages/start-vercel) for SolidStart.
+
+```bash
+npm run build
+```
