 ## Usage
 Those templates dependencies are maintained via [pnpm](https://pnpm.io) via `pnpm up -Lri`.
 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
 ```
 ### Learn more on the [Solid Website](https://solidjs.com) and come chat with us on our [Discord](https://discord.com/invite/solidjs)
 ## Available Scripts
 In the project directory, you can run:
 ### `npm 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.)
