 ## What is Headless WordPress?
 
-When we talk about headless with WordPress, we mean using WordPress for content creation but not for front-end rendering. Instead of using traditional WordPress themes, you develop your front-end using a JavaScript framework like React. Also, the front-end is hosted on a separate server from the WordPress instance.
+When we talk about headless with WordPress, we mean using WordPress for content creation but not for front-end rendering. Instead of using traditional WordPress themes, you develop your front-end using a JavaScript framework like React. A separate server hosts the front-end from the WordPress instance.
 
 Since the front-end is responsible for displaying content to the end-user, it needs to access the content. To do that, it utilized the WordPress REST API or GraphQL via [WPGraphQL](https://www.wpgraphql.com/).
 
 ## Why Headless?
 
 Headless is gaining momentum for a few reasons:
 
-- Developer Choice - developers want to use modern frameworks like React to build sites and applications, and headless enables that possibility.
-- Scalability - When you remove the burden of WordPress's rendering, you reduce the load on your WordPress instance, which allows WordPress to scale much more manageable.
-- Security - Removing the responsibility of rendering from WordPress minimizes the surface area for attacks. Now, you can choose only to expose the API to the internet.
-- Integrations - The WordPress community indeed provides many integrations through plugins, but they don't always work well together. When you go headless, you have more control over your integrations, and most services support integrating with JavaScript and Node.js.

 ## Connecting Your WordPress Backend
 
-Each app environment pairs with a WordPress backend. In the [WP Engine User Portal](https://my.wpengine.com), the WordPress equivalent to an _app_ is a _site_. A site has environments just like apps. Each _app environment_ needs to pair with a `_site environment_` via the site's environment id found in the user portal. You make the connection by setting the `wp_environment_name` property for each environment in your app config.
