 Marko makes it easy to to co-locate your component's class and styles with the HTML view that they correspond to. The following are the key part of any UI component:
 
-- __View__ - The HTML template for your UI component. Receives input properties and states and renders to either HTML (server-side) or virtual DOM nodes (browser-side)
-- __Client-side behavior__ - Implemented as a JavaScript class with methods and properties to provide initialization, event handling (including DOM events, custom events and lifecycle events) and state management

+* **Styling** - Cascading StyleSheet with support for CSS preprocessors such as Less or Sass
 
 ## Server-side rendering
 
 A UI component can be rendered on the server or in the browser, but in either case, the UI component instance will be mounted to a DOM node in the browser automatically. If a UI component tree is rendered on the server then Marko will automatically recreate the UI component tree in the browser with no extra code required. For more details, please see [Server-side rendering](/docs/server-side-rendering/).

 ## Split components
 
-Split components allow you to optimize for the case where a component is rendered on the server, but doesn't need to be re-rendered in the browser.  Because the component doesn't need to be rendered in the browser, the template does not need to be sent to the browser.  This can reduce your page weight by a few hundred bytes in some cases.
+Split components allow you to optimize for the case where a component is rendered on the server, but doesn't need to be re-rendered in the browser. Because the component doesn't need to be rendered in the browser, the template does not need to be sent to the browser. This can reduce your page weight by a few hundred bytes in some cases.
 
 > **Note:** If a split component is the child of a stateful component, the full rendering logic will still be sent down because the parent component may pass new input to the split component, requiring it to re-render.
 
 Additionally if _all_ components rendered on a page are split components, Marko's VDOM and rendering runtime is not necessary and therefore not sent to the browser, which can further reduce page weight by a few kilobytes.
 
-> **ProTip:** Don't over-optimize.  If your component really doesn't need re-rendering, go ahead and split, but don't forgo stateful re-rendering when it would make your code more maintainable.

 ### Usage
 
 Marko discovers split components in a similar way to how it discovers an external component class:
-for example if you have a view named `button.marko`, it will automatically look for `button.component-browser.js`.  If your view is named `index.marko`, it will look for `component-browser.js` in addition to `index.component-browser.js`.
+for example if you have a view named `button.marko`, it will automatically look for `button.component-browser.js`. If your view is named `index.marko`, it will look for `component-browser.js` in addition to `index.component-browser.js`.

-A split component might also need to do some set up as part of the initial render.  In this case, the component may define a second component class to use the `onCreate`, `onInput`, and `onRender` [lifecycle methods](#lifecycle-events).  This class can be exported from `component.js` or defined right in the template as with single-file components.

 Emits a UI component custom event. If a UI component attached a listener with the matching `eventName` then the corresponding event listener method will be automatically invoked. Event listeners can be attached using either the [`on-[event](methodName, ...args)` attribute](#declarative-custom-events) attribute or `targetComponent.on()`.

+The built in view engine for express may be asynchronous, but it doesn't support streaming (check out [Rediscovering Progressive HTML Rendering](http://www.ebaytechblog.com/2014/12/08/async-fragments-rediscovering-progressive-html-rendering-with-marko/) to see why this is so important). So instead we'll [bypass the view engine](https://strongloop.com/strongblog/bypassing-express-view-rendering-for-speed-and-modularity/).
 
 ## Usage
 
-Marko provides a submodule (`marko/express`) to add a `res.marko` method to the express response object.  This function works much like `res.render`, but doesn't impose the restrictions of the express view engine and allows you to take full advantage of Marko's streaming and modular approach to templates.

+A big part of this release is a shift in focus from Marko being merely a templating language to a complete UI library. As such, we are providing first-class support for components.
 
 You will no longer need to install `marko-widgets` as an external library, and there is more cohesion between the templates and components/components.

 Marko allows any Marko template/UI component to be rendered on the server or in the browser. A page can be rendered to a `Writable` stream such as an HTTP response stream as shown below:
