Bootstrap is a sleek, intuitive, and powerful front-end framework for faster and easier web development, created and maintained by [Mark Otto](http://twitter.com/mdo) and [Jacob Thornton](http://twitter.com/fat).
Read the [Getting Started page](http://getbootstrap.com/getting-started/) for information on the framework contents, basic template guidelines, and more.
Have a bug or a feature request? [Please open a new issue](https://github.com/twitter/bootstrap/issues). Before opening any issue, please search for existing issues and read the [Issue Guidelines](https://github.com/necolas/issue-guidelines), written by [Nicolas Gallagher](https://github.com/necolas/).
Bootstrap's docs are built using [Jekyll](http://jekyllrb.com) and hosted on GitHub Pages at [http://getbootstrap.com](http://getbootstrap.com). To view our docs locally, you'll need to [install Jekyll](https://github.com/mojombo/jekyll/wiki/install) to run a local server.
Bootstrap includes a [makefile](Makefile) with convenient methods for working with the framework. Before getting started, be sure to install [the necessary local dependencies](package.json):
Should you encounter problems with installing dependencies or running the makefile commands, be sure to first uninstall any previous versions (global and local) you may have installed, and then rerun `npm install`.
Please submit all pull requests against *-wip branches. 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).
For transparency and insight into our release cycle, and for striving to maintain backward compatibility, Bootstrap will be maintained under the Semantic Versioning guidelines as much as possible.
Releases will be numbered with the following format:
`<major>.<minor>.<patch>`
And constructed with the following guidelines:
* Breaking backward compatibility bumps the major (and resets the minor and patch)
* New additions without breaking backward compatibility bumps the minor (and resets the patch)
* Bug fixes and misc changes bumps the patch
