Read the Getting started page for information on the framework contents, templates and examples, and more.

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.css.map
│   ├── bootstrap.min.css
│   ├── bootstrap-theme.css
│   ├── bootstrap-theme.css.map
│   └── 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
    └── glyphicons-halflings-regular.woff2

We provide compiled CSS and JS (bootstrap.*), as well as compiled and minified CSS and JS (bootstrap.min.*). CSS source maps (bootstrap.*.map) are available for use with certain browsers' developer tools. Fonts from Glyphicons are included, as is the optional Bootstrap theme.

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.

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

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

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

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

Learn more about using Jekyll by reading its documentation.

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

Previous releases and their documentation are also available for download.

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.

Editor preferences are available in the editor config for easy use in common text editors. Read more and download plugins at https://editorconfig.org.

Keep track of development and community news.

• Follow @getbootstrap on Twitter.
• Read and subscribe to The Official Bootstrap Blog.
• Chat with fellow Bootstrappers in IRC. On the irc.freenode.net server, in the ##bootstrap channel.
• Implementation help may be found at Stack Overflow (tagged twitter-bootstrap-3).
• Developers should use the keyword bootstrap on packages which modify or add to the functionality of Bootstrap when distributing through npm or similar delivery mechanisms for maximum discoverability.

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.
