+# Welcome to [Astro](https://astro.build) - [nanostores](https://github.com/nanostores/nanostores)
+
+This is a test of a shared store between components from different frameworks/libs using [nanostores](https://github.com/nanostores/nanostores).
+
+## 🚀 Project Structure
+
+Inside of your Astro project, you'll see the following folders and files:
+
+```
+/
+├── public/
+│   ├── robots.txt
+│   └── favicon.ico
+├── src/
+│   ├── components/
+│   │   └── Tour.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.
+
+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 start` | Starts local dev server at `localhost:3000` |
+| `npm run build` | Build your production site to `./dist/`     |
+
