**Knockout** is a JavaScript [MVVM](http://en.wikipedia.org/wiki/Model_View_ViewModel) (a modern variant of MVC) library that makes it easier to create rich, desktop-like user interfaces with JavaScript and HTML. It uses *observers* to make your UI automatically stay in sync with an underlying data model, along with a powerful and extensible set of *declarative bindings* to enable productive development.
##Getting started
[![Join the chat at https://gitter.im/knockout/knockout](https://badges.gitter.im/Join%20Chat.svg)](https://gitter.im/knockout/knockout?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)
**Totally new to Knockout?** The most fun place to start is the [online interactive tutorials](http://learn.knockoutjs.com/).
For more details, see
* Documentation on [the project's website](http://knockoutjs.com/documentation/introduction.html)
* Online examples at [http://knockoutjs.com/examples/](http://knockoutjs.com/examples/)
##Downloading Knockout
You can [download released versions of Knockout](http://knockoutjs.com/downloads/) from the project's website.
For Node.js developers, Knockout is also available from [npm](https://npmjs.org/) - just run `npm install knockout`.
##Building Knockout from sources
If you prefer to build the library yourself:
1. **Clone the repo from GitHub**
git clone https://github.com/knockout/knockout.git
cd knockout
2. **Acquire build dependencies.** Make sure you have [Node.js](http://nodejs.org/) installed on your workstation. This is only needed to _build_ Knockout from sources. Knockout itself has no dependency on Node.js once it is built (it works with any server technology or none). Now run:
npm install -g grunt-cli
npm install
The first `npm` command sets up the popular [Grunt](http://gruntjs.com/) build tool. You might need to run this command with `sudo` if you're on Linux or Mac OS X, or in an Administrator command prompt on Windows. The second `npm` command fetches the remaining build dependencies.
3. **Run the build tool**
grunt
Now you'll find the built files in `build/output/`.
## Running the tests
If you have [phantomjs](http://phantomjs.org/download.html) installed, then the `grunt` script will automatically run the specification suite and report its results.
Or, if you want to run the specs in a browser (e.g., for debugging), simply open `spec/runner.html` in your browser.

// text(value) - writes the supplied template text to your storage location
// data(key) - reads values stored using data(key, value) - see below
// data(key, value) - associates "value" with this template and the key "key". Is used to store information like "isRewritten".
