+# create a new project in my-app
+npm create svelte@latest my-app
 ```
 
 ## Developing
 
-Once you've created your project, follow these steps:
+Once you've created a project and installed dependencies with `npm install` (or `pnpm install` or `yarn`), start a development server:
 
-1: Delete package-lock.json
+```bash
-2: Check `git status`. If you see any changes other than package-lock.json or favicon.ico, run the command `git restore ./` (See below)
+npm run dev
-3: Run `npm install` or `pnpm install` or `yarn` to install the dependencies
-4: Run `npm run build` to build the project
 
-Running `git status` should show:
+# or start the server and open the app in a new browser tab
+npm run dev -- --open
+```

+## Building
+
+To create a production version of your app:
+
+```bash
+npm run build
+```
 
 You can preview the production build with `npm run preview`.
