   <h2>Pre-rendering</h2>
   <p>
-    With Jamstack, the entire front end is prebuilt into highly optimized static pages and assets during a build process. This process of pre-rending results in sites which can be served directly from a <a href="/glossary/cdn">CDN</a>, reducing the cost, complexity and risk, of dynamic servers as cirticial infrastructure.

   <h2>Enhancing with JavaScript</h2>
   <p>
-    With the <a href="/glossary/markup">markup</a> and other user interface assets of Jamstack sites served directly from a CDN, they can be delivered very quickly and securely. On this foundation, Jamstack sites can use JavaScript and APIs to talk to backend services, allowing experiences to be enhanced and personalized.

+  <h2>Supercharging with services</h2>
+  <p>
+    The thriving <a hred="/glossary/api-economy/">API economy</a> has become a significant enabler for Jamstack sites. The ability to leverage domain experts who offer their products and service via APIs has allowed teams to build for more complex applications than if they were to take on the risk and burden of such capabilities themselves. Now we can outsource things like authentication and identity, payments, content management, data services, search, and much more.
+    </p>
+  <p>
+    Jamstack sites might utilise such services at build time, and also at run time directly from the browser via JavaScript. And the clean <a href="/glossary/decoupling/">decoupling</a> of these services allows for greater portability and flexibility, as well as significanlty reduced risk.

   <h2>Named to help the conversation</h2>
   <p>
-    The name "Jamstack" came about because as Matt Biilmann and Chris Bach were creating modern web development workflows and capabilities at Netlify, they found there was no easy way to refer to the architectural approach in conversation. Jamstack embraces many existing fundamentals of web architectures, and so they created the term Jamstack to help us talk about it more succinctly.
