+
+  <p>Angular is a platform that makes it easy to build applications with the web. Angular
+    combines declarative templates, dependency injection, end to end tooling, and integrated
+    best practices to solve development challenges. Angular empowers developers to build
+    applications that live on the web, mobile, or the desktop</p>
+
+  <h3>Architecture overview</h3>
+
+  <p>Angular is a platform and framework for building client applications in HTML and TypeScript.
+  Angular is itself written in TypeScript. It implements core and optional functionality as a
+  set of TypeScript libraries that you import into your apps.</p>
+
+  <p>The basic building blocks of an Angular application are NgModules, which provide a compilation
+  context for components. NgModules collect related code into functional sets; an Angular app is
+  defined by a set of NgModules. An app always has at least a root module that enables
+  bootstrapping, and typically has many more feature modules.</p>
+
+  <p>Components define views, which are sets of screen elements that Angular can choose among and
+  modify according to your program logic and data. Every app has at least a root component.</p>
+
+  <p>Components use services, which provide specific functionality not directly related to views.
+  Service providers can be injected into components as dependencies, making your code modular,
+  reusable, and efficient.</p>
+
+  <p>Both components and services are simply classes, with decorators that mark their type and
+  provide metadata that tells Angular how to use them.</p>
+
+  <p>The metadata for a component class associates it with a template that defines a view. A
+  template combines ordinary HTML with Angular directives and binding markup that allow Angular
+  to modify the HTML before rendering it for display.</p>
+
+  <p>The metadata for a service class provides the information Angular needs to make it available
+  to components through Dependency Injection (DI).</p>
+
+  <p>An app's components typically define many views, arranged hierarchically. Angular provides
+  the Router service to help you define navigation paths among views. The router provides
+  sophisticated in-browser navigational capabilities.</p>
