+
+<h5 class="text-2xl pt-4">Why TanStack Query?</h5>
+<p>
+  In this demo you will be able to see how TanStack Query is a significant
+  improvement over <strong>redux</strong>, <strong>mobx</strong>, and any other
+  general-purpose state container.
+</p>
+<p>
+  No reducers, thunks, or sagas. No ES6 models to maintain in order to tag them
+  as observable.
+</p>
+<p>
+  Simply associate a key with your fetch call and let{' '}
+  <strong>TanStack Query</strong> handle the rest.
+</p>
+<h5 class="text-2xl pt-4">Ready to get started?</h5>
