Bootstrap is a sleek, intuitive, and powerful front-end framework for faster and easier web development, created by [Mark Otto](http://twitter.com/mdo) and [Jacob Thornton](http://twitter.com/fat), and maintained by the [core team](https://github.com/twbs?tab=members) with the massive support and involvement of the community.
Within the download you'll find the following directories and files, logically grouping common assets and providing both compiled and minified variations. You'll see something like this:
```
bootstrap/
├── css/
│ ├── bootstrap.css
│ ├── bootstrap.min.css
│ ├── bootstrap-theme.css
│ └── bootstrap-theme.min.css
├── js/
│ ├── bootstrap.js
│ └── bootstrap.min.js
└── fonts/
├── glyphicons-halflings-regular.eot
├── glyphicons-halflings-regular.svg
├── glyphicons-halflings-regular.ttf
└── glyphicons-halflings-regular.woff
```
We provide compiled CSS and JS (`bootstrap.*`), as well as compiled and minified CSS and JS (`bootstrap.min.*`). Fonts from Glyphicons are included, as is the optional Bootstrap theme.
Have a bug or a feature request? Please first read the [issue guidelines](https://github.com/twbs/bootstrap/blob/master/CONTRIBUTING.md#using-the-issue-tracker) and search for existing and closed issues. If your problem or idea is not addressed yet, [please open a new issue](https://github.com/twbs/bootstrap/issues/new).
Bootstrap's documentation, included in this repo in the root directory, is built with [Jekyll](http://jekyllrb.com) and publicly hosted on GitHub Pages at <http://getbootstrap.com>. The docs may also be run locally.
- **Windows users:** For Ruby 2.0.0 run `chcp 65001` first to change the command prompt's character encoding ([code page](http://en.wikipedia.org/wiki/Windows_code_page)) to UTF-8 so Jekyll runs without errors. For Ruby 1.9.3 you can alternatively do `SET LANG=en_EN.UTF-8`. In addition, ensure you have Python installed and added in your `PATH` or the build will fail due to our Pygments dependency.
Bootstrap uses [Grunt](http://gruntjs.com/) with convenient methods for working with the framework. It's how we compile our code, run tests, and more. To use it, install the required dependencies as directed and then run some Grunt commands.
2. Navigate to the root `/bootstrap` directory, then run `npm install`. npm will look at [package.json](package.json) and automatically install the necessary local dependencies listed there.
**Unfamiliar with `npm`? Don't have node installed?** That's a-okay. npm stands for [node packaged modules](http://npmjs.org/) and is a way to manage development dependencies through node.js. [Download and install node.js](http://nodejs.org/download/) before proceeding.
Run `grunt` to run tests locally and compile the CSS and JavaScript into `/dist`. **Uses [recess](http://twitter.github.io/recess/) and [UglifyJS](http://lisperator.net/uglifyjs/).**
`grunt dist` creates the `/dist` directory with compiled files. **Uses [recess](http://twitter.github.io/recess/) and [UglifyJS](http://lisperator.net/uglifyjs/).**
Should you encounter problems with installing dependencies or running Grunt commands, uninstall all previous dependency versions (global and local). Then, rerun `npm install`.
Please read through our [contributing guidelines](https://github.com/twbs/bootstrap/blob/master/CONTRIBUTING.md). Included are directions for opening issues, coding standards, and notes on development.
More over, if your pull request contains JavaScript patches or features, you must include relevant unit tests. All HTML and CSS should conform to the [Code Guide](http://github.com/mdo/code-guide), maintained by [Mark Otto](http://github.com/mdo).
Editor preferences are available in the [editor config](.editorconfig) for easy use in common text editors. Read more and download plugins at <http://editorconfig.org>.
For transparency into our release cycle and in striving to maintain backward compatibility, Bootstrap is maintained under the Semantic Versioning guidelines. Sometimes we screw up, but we'll adhere to these rules whenever possible.
