+
+## 🚀 Project Structure
+
+Inside of your Astro project, you'll see the following folders and files:
+
+```
+/
+├── public/
+├── src/
+│   └── pages/
+│       └── index.astro
+└── package.json
+```
+
+Astro looks for `.astro` or `.md` files in the `src/pages/` directory. Each page is exposed as a route based on its file name.
+
+There's nothing special about `src/components/`, but that's where we like to put any Astro/React/Vue/Svelte/Preact components.
+
+Any static assets, like images, can be placed in the `public/` directory.
+
+## 🧞 Commands
+
+All commands are run from the root of the project, from a terminal:
+
+| Command                | Action                                           |
+| :--------------------- | :----------------------------------------------- |
+| `npm install`          | Installs dependencies                            |
+| `npm run dev`          | Starts local dev server at `localhost:3000`      |
+| `npm run build`        | Build your production site to `./dist/`          |
+| `npm run preview`      | Preview your build locally, before deploying     |
+| `npm run astro ...`    | Run CLI commands like `astro add`, `astro check` |
+| `npm run astro --help` | Get help using the Astro CLI                     |
