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.min.css.map │ ├── bootstrap-theme.css │ ├── bootstrap-theme.css.map │ ├── bootstrap-theme.min.css │ └── bootstrap-theme.min.css.map ├── 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.
Note that feature requests must target Bootstrap v4, because Bootstrap v3 is now in maintenance mode and is closed off to new features. This is so that we can focus our efforts on Bootstrap v4.
- If necessary, install Jekyll and other Ruby dependencies with
bundle install. Note for Windows users: Read this unofficial guide to get Jekyll up and running without problems.

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.
Please read through our contributing guidelines. Included are directions for opening issues, coding standards, and notes on development.
Bootstrap v3 is now closed off to new features. It has gone into maintenance mode so that we can focus our efforts on Bootstrap v4, the future of the framework. Pull requests which add new features (rather than fix bugs) should target Bootstrap v4 (the
v4-dev git branch) instead.

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.
