-### Why is this project called "angular"? Why is the namespace called "ng"?
+### Why is this project called "AngularJS"? Why is the namespace called "ng"?
 
-Because HTML has angular brackets and "ng" sounds like "angular".
+Because HTML has Angular brackets and "ng" sounds like "Angular".
 
-### Is <angular/> an HTML5 tag?
 
-No, <angular/> is not an HTML5 tag. angular is an orthogonal project to HTML5; you can use the two
-together.
+### Is AngularJS a library, framework, plugin or a browser extension?
 
-### Is angular a {library, framework, DOM manipulation library, widget library, native plugin}?
+AngularJS fits the definition of a framework the best, even though it's much more lightweight than
+a typical framework and that's why many confuse it with a library.
 
-No, angular is none of these. You don't call its functions, it does not call your functions,
-it does not provide a way to manipulate DOM, but does provide primitives to create UI projections
-of your data. There are lots of existing widget libraries which you can integrate with angular.
-It is 100% JavaScript, 100% client side and compatible with both desktop and mobile browsers.
+AngularJS is 100% JavaScript, 100% client side and compatible with both desktop and mobile browsers.
+So it's definitely not a plugin or some other native browser extension.

+### Is AngularJS a templating system?
+
+At the highest level, Angular does look like a just another templating system. But there is one
+important reason why Angular templating system is different and makes it very good fit for
+application development: bidirectional data binding. The template is compiled in the browser and
+the compilation step produces a live view. This means you, the developers, don't need to write
+code to constantly sync the view with the model and the model with the view as in other
+templating systems.

+### Do I need to worry about security holes in AngularJS?

+Like with any technology, AngularJS is not impervious to attack. angular does, however, provide
 built-in protection from basic security holes including cross-site scripting and HTML injection
-attacks. angular does round-trip escaping on all strings for you.
+attacks. AngularJS does round-trip escaping on all strings for you and even offers XSRF protection
+for server-side communication.
+
+AngularJS was designed to be compatible with other security measures like Content Security Policy
+(CSP), HTTPS (SSL/TLS) and server-side authentication and authorization that greatly reduce the
+possible attack vectors and we highly recommended their use.

 Yes. See instructions in {@link downloading}.

 ### What browsers does angular work with?
 
-Webkit-based browsers (Safari, Chrome, iPhone, Android, WebOS, BlackBerry 6), Firefox, IE6 and
-above. Note that CSS only works on IE7 and above.
+Our we run our extensive test suite against the following browsers: Safari, Chrome, Firefox, Opera,
+IE8, IE9 and mobile browsers (Android, Chrome Mobile, iOS Safari).
+
+
+### What's Angular's performance like?
+
+The startup time heavily depends on your network connection, state of the cache, browser used and
+available hardware, but typically we measure bootstrap time in tens or hundreds of milliseconds.
 
-### What's angular's performance like?
+The runtime performance will vary depending on the number and complexity of bindings on the page
+as well as the speed of your backend (for apps that fetch data from the backend). Just for an
+illustration we typically build snappy apps with hundreds or thousands of active bindings.
 
-angular takes ~300ms to load, render, and compile. In Chrome it uses about 2-5MB of memory. Your
-app's performance will vary depending on how many bindings you use.
 
-### How big is the angular bootstrap JS file that I need to include?
+### How big is the angular.js file that I need to include?
+
+The size of the file is < 29KB compressed and minified.
 
-The size of the library itself is < 50KB compressed and obfuscated.
 
 ### Can I use the open-source Closure Library with angular?

 ### Does angular use the jQuery library?
 
-Yes, angular uses {@link http://jquery.com/ jQuery}, the open source DOM manipulation library.
-If jQuery is not present in your script path, angular falls back on its own implementation of
-{@link api/angular.element jQuery lite}. If jQuery is present in the path, angular uses it to
-manipulate the DOM.
+Yes, Angular can use {@link http://jquery.com/ jQuery} if it's present in your app when the
+application is being bootstrapped. If jQuery is not present in your script path, Angular falls back
+to its own implementation of the subset of jQuery that we call {@link api/angular.element  jQLite}.

 ### What is testability like in angular?
 
-Very testable. It has an integrated dependency injection framework. See
+Very testable and designed this way from ground up. It has an integrated dependency injection
+framework, provides mocks for many heavy dependencies (server-side communication). See
 {@link api/ng service} for details.
