+## Deploying to Netlify
+
+[![Deploy to Netlify](https://www.netlify.com/img/deploy/button.svg)](https://app.netlify.com/start/deploy?repository=https://github.com/netlify-templates/astro-platform-starter)
+
+## Developing Locally
+
+| Prerequisites             |
+| :------------------------ |
+| [Node.js](https://nodejs.org/) v18.14+. |
+| (optional) [nvm](https://github.com/nvm-sh/nvm) for Node version management. |
+
+1. Clone this repository, then run `npm install` in its root directory.
+
+2. For the starter to have full functionality locally (e.g. edge functions, blob store), please ensure you have an up-to-date version of Netlify CLI. Run:
+
+```
+npm install netlify-cli@latest -g
+```
+
+3. Link your local repository to the deployed Netlify site. This will ensure you're using the same runtime version for both local development and your deployed site.
+
+```
+netlify link
+```
+
+4. Then, run the Astro.js development server via Netlify CLI:
+
+```
+netlify dev
+```
+
+If your browser doesn't navigate to the site automatically, visit [localhost:8888](http://localhost:8888).
