+# create-astro
+## Scaffolding for Astro projects
+
+**With NPM:**
+```bash
+npm init astro
+```
+
+**With Yarn:**
+```bash
+yarn create astro
+```
+
+`create-astro` automatically runs in _interactive_ mode, but you can also specify your project name and template with command line arguments.
+
+```bash
+# npm 6.x
+npm init astro my-astro-project --template blank
+
+# npm 7+, extra double-dash is needed:
+npm init astro my-astro-project -- --template blank
+
+# yarn
+yarn create astro my-astro-project --template blank
+```
+
+To see all available options, use the `--help` flag.
+
+### Templates
+
+The following templates are included:
+
+- `starter`
+- `blank`
+
+Feel free to [open a PR](https://github.com/snowpackjs/astro/pulls) to add additional templates.

+# Welcome to [Astro](https://astro.build)
+
+> 🧑‍🚀 **Seasoned astronaut?** Delete this file. Have fun!
+
+## 🚀 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.astro` files in the `src/pages/` directory. Each page is exposed as a route based on its file name.
+
+Any static assets, like images, can be placed in the `public/` directory.
