-## Usage
+# test
 
-Those templates dependencies are maintained via [pnpm](https://pnpm.io) via `pnpm up -Lri`.
+To install dependencies:
-
-This is the reason you see a `pnpm-lock.yaml`. That being said, any package manager will work. This file can be safely be removed once you clone a template.
 
 ```bash
-$ npm install # or pnpm install or yarn install
+bun install
 ```
 
-### Learn more on the [Solid Website](https://solidjs.com) and come chat with us on our [Discord](https://discord.com/invite/solidjs)
+To run:
 
-## Available Scripts
+```bash
+bun run index.js
+```
 
-In the project directory, you can run:
+This project was created using `bun init` in bun v1.1.20. [Bun](https://bun.sh) is a fast all-in-one JavaScript runtime.
-
-### `npm run dev` or `npm start`
-
-Runs the app in the development mode.<br>
-Open [http://localhost:3000](http://localhost:3000) to view it in the browser.
-
-The page will reload if you make edits.<br>
-
-### `npm run build`
-
-Builds the app for production to the `dist` folder.<br>
-It correctly bundles Solid in production mode and optimizes the build for the best performance.
-
-The build is minified and the filenames include the hashes.<br>
-Your app is ready to be deployed!
-
-## Deployment
-
-You can deploy the `dist` folder to any static host provider (netlify, surge, now, etc.)
-
-## This project was created with the [Solid CLI](https://solid-cli.netlify.app)
