-The way it is able to figure this out is that React does not directly manipulate the DOM. **It uses a fast, internal mock DOM to perform diffs and computes the most efficient DOM mutation for you.**

 ## Components are Just Like Functions
 
 React components are very simple. You can think of them as simple function that take in `props` and `state` (discussed later) and render HTML. Because they're so simple, it makes them very easy to reason about.
 
-**One limitation**: React components can only render a single root node. If you want to return multiple nodes they *must* be wrapped in a single root. This is a limitation we can fix, but we have not identified a pressing reason to do so yet; reach out to our [Google Group](http://groups.google.com/group/reactjs) if you have a compelling case for it.

 ## JSX Syntax
 
 We strongly believe that components are the right way to separate concerns rather than "templates" and "display logic." We think that markup and the code that generates it are intimately tied together. Additionally, display logic is often very complex and using template languages to express it becomes cumbersome.
 
-We've found that the best solution for this problem is to generate markup directly from the JavaScript code such that you can use all of the expressive power of a real programming language to build UIs. In order to make this easier, we've added a *very* simple, **optional** HTML-like syntax for the function calls that generate markup called JSX.

-**JSX lets you write JavaScript function calls with HTML syntax.** To generate, say, a link using pure JavaScript you'd write: `React.DOM.a({href: 'http://facebook.github.io/react/'}, 'Hello React!')`. With JSX this becomes `<a href="http://facebook.github.io/react/">Hello React!</a>`. We've found this has made building React apps easier and designers tend to prefer the syntax, but everyone has their own workflow, so **JSX is not required to use React.**

 JSX is very small; the "hello, world" example above uses every feature of JSX. To learn more about it, see [JSX in depth](./02.1-jsx-in-depth.html). Or see the transform in action in [our live JSX compiler](/react/jsx-compiler.html).
 
 JSX is similar to HTML, but not exactly the same. See [JSX gotchas](./02.2-jsx-gotchas.html) for some key differences.
 
-The easiest way to get started with JSX is to use the in-browser `JSXTransformer`, but in production you'll want to precompile your code using our command-line [react-tools](http://npmjs.org/package/react-tools) package.
