+# Starlight Starter Kit: Basics
+
+[![Built with Starlight](https://astro.badg.es/v2/built-with-starlight/tiny.svg)](https://starlight.astro.build)
+
+```
+pnpm create astro@latest -- --template starlight
+```
+
+> 🧑‍🚀 **Seasoned astronaut?** Delete this file. Have fun!
+
+## 🚀 Project Structure
+
+Inside of your Astro + Starlight project, you'll see the following folders and files:
+
+```
+.
+├── public/
+├── src/
+│   ├── assets/
+│   ├── content/
+│   │   └── docs/
+│   └── content.config.ts
+├── astro.config.mjs
+├── package.json
+└── tsconfig.json
+```
+
+Starlight looks for `.md` or `.mdx` files in the `src/content/docs/` directory. Each file is exposed as a route based on its file name.
+
+Images can be added to `src/assets/` and embedded in Markdown with a relative link.
+
+Static assets, like favicons, can be placed in the `public/` directory.
+
+## 🧞 Commands
+
+All commands are run from the root of the project, from a terminal:
+
+| Command                   | Action                                           |
+| :------------------------ | :----------------------------------------------- |
+| `pnpm install`             | Installs dependencies                            |
+| `pnpm dev`             | Starts local dev server at `localhost:4321`      |
+| `pnpm build`           | Build your production site to `./dist/`          |
+| `pnpm preview`         | Preview your build locally, before deploying     |
+| `pnpm astro ...`       | Run CLI commands like `astro add`, `astro check` |
+| `pnpm astro -- --help` | Get help using the Astro CLI                     |
