**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
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
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**
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.
