+# Welcome to [Astro](https://astro.build)
+
+[![Open in StackBlitz](https://developer.stackblitz.com/img/open_in_stackblitz.svg)](https://stackblitz.com/github/withastro/astro/tree/latest/examples/starter)
+
+> 🧑‍🚀 **Seasoned astronaut?** Delete this file. Have fun!
+
+## 🚀 Project Structure
+
+Inside of your Astro project, you'll see the following folders and files:
+
+```
+/
+├── public/
+│   └── favicon.ico
+├── src/
+│   ├── components/
+│   │   └── Layout.astro
+│   └── 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 or layouts.
+
+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 |
