What's included

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.

Bugs and feature requests

Have a bug or a feature request? Please first read the issue guidelines and search for existing and closed issues. If your problem or idea is not addressed yet, please open a new issue.

Documentation

Bootstrap's documentation, included in this repo in the root directory, is built with Jekyll and publicly hosted on GitHub Pages at http://getbootstrap.com. The docs may also be run locally.

Running documentation locally

If necessary, install Jekyll (requires v2.5.x).

Windows users: Read this unofficial guide to get Jekyll up and running without problems.

Install the Ruby-based syntax highlighter, Rouge, with gem install rouge.
From the root /bootstrap directory, run jekyll serve in the command line.
Open http://localhost:9001 in your browser, and voilà.

Learn more about using Jekyll by reading its documentation.

Documentation for previous releases

Documentation for v2.3.2 has been made available for the time being at http://getbootstrap.com/2.3.2/ while folks transition to Bootstrap 3.

Previous releases and their documentation are also available for download.

Contributing

Please read through our contributing guidelines. Included are directions for opening issues, coding standards, and notes on development.

Moreover, 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, maintained by Mark Otto.

Issues and labels

Our bug tracker utilizes several labels to help organize and identify issues. Here's what they represent and how we use them:

browser bug - Issues that are reported to us, but actually are the result of a browser-specific bug. These are diagnosed with reduced test cases and result in a issue opened on that browser's own bug tracker.
confirmed - Issues that have been confirmed with a reduced test case and idenfity a bug in Bootstrap.
css - Issues stemming from our compiled CSS or source Less files.
customizer - Issues with our web-based Customizer.
docs - Issues for improving or updating our documentation.
examples - Issues involving the example templates included in our docs.
feature - Issues asking for a new feature to be added, or an existing one to be extended or modified. New features require a minor version bump (e.g., v3.0.0 to v3.1.0).
grunt - Issues with our included JavaScript-based Gruntfile, which is used to run all our tests, concatenate and compile source files, and more.
help wanted - Issues we need or would love help from the community to resolve.
js - Issues stemming from our compiled or source JavaScript files.
meta - Issues with the project itself or our GitHub repository.

For a complete look at our labels, see the project labels page.

Versioning

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 those rules whenever possible.
