+## Why Astro Netlify
+
+If you're using Astro as a static site builder—its behavior out of the box—you don't need an adapter.
+
+If you wish to [use server-side rendering (SSR)](https://docs.astro.build/en/guides/server-side-rendering/), Astro requires an adapter that matches your deployment runtime.
+
+[Netlify](https://www.netlify.com/) is a deployment platform that allows you to host your site by connecting directly to your GitHub repository. This adapter enhances the Astro build process to prepare your project for deployment through Netlify.
+
+
+## Installation
+
+First, install the `@astrojs/netlify` package using your package manager. If you're using npm or aren't sure, run this in the terminal:
+```sh
+npm install @astrojs/netlify
+```
+
+Then, install this adapter in your `astro.config.*` file using the `adapter` property. Note: there are two different adapters, one for Netlify Functions and one for Edge Functions. See [Edge Functions](#edge-functions) below on importing the latter.

-## Edge Functions
+### Edge Functions
 
 Netlify has two serverless platforms, Netlify Functions and Netlify Edge Functions. With Edge Functions your code is distributed closer to your users, lowering latency. You can use Edge Functions by changing the import in your astro configuration file:

+## Usage
+
+[Read the full deployment guide here.](https://docs.astro.build/en/guides/deploy/vercel)
+
+After [performing a build](https://docs.astro.build/en/guides/deploy/#building-the-app) the `netlify/` folder will contain [Netlify Functions](https://docs.netlify.com/functions/overview/) in the `netlify/functions/` folder.
+
+Now you can deploy. Install the [Netlify CLI](https://docs.netlify.com/cli/get-started/) and run:
+
+```shell
+netlify deploy --build
+```
+
+The [Netlify Blog post on Astro](https://www.netlify.com/blog/how-to-deploy-astro/) and the [Netlify Documentation](https://docs.netlify.com/integrations/frameworks/astro/) provide more information on how to use this integration to deploy to Netlify.
