 ## Quick start

 Several quick start options are available:

 * [Download the latest release](https://github.com/twbs/bootstrap/archive/v3.4.1.zip).
 * Clone the repo: `git clone https://github.com/twbs/bootstrap.git`.
 * Install with [Bower](https://bower.io/): `bower install bootstrap`.
 * Install with [npm](https://www.npmjs.com/): `npm install bootstrap@3`.
 * Install with [Meteor](https://www.meteor.com/): `meteor add twbs:bootstrap`.
 * Install with [Composer](https://getcomposer.org/): `composer require twbs/bootstrap`.

 Read the [Getting started page](https://getbootstrap.com/docs/3.4/getting-started/) for information on the framework contents, templates and examples, and more.

 ### 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.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](https://developers.google.com/web/tools/chrome-devtools/javascript/source-maps) (`bootstrap.*.map`) are available for use with certain browsers' developer tools. 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](https://github.com/twbs/bootstrap/blob/v3-dev/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).

 Note that **feature requests must target [Bootstrap v4](https://github.com/twbs/bootstrap/tree/v4-dev),** 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.


 ## Documentation

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

 ### Running documentation locally

 1. If necessary, [install Jekyll](https://jekyllrb.com/docs/installation/) and other Ruby dependencies with `bundle install`.
    **Note for Windows users:** Read [this guide](https://jekyllrb.com/docs/installation/windows/) to get Jekyll up and running without problems.
 2. From the root `/bootstrap` directory, run `bundle exec jekyll serve` in the command line.
 4. Open `http://localhost:9001` in your browser, and voilà.

 Learn more about using Jekyll by reading its [documentation](https://jekyllrb.com/docs/).

 ### Documentation for previous releases

 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](https://github.com/twbs/bootstrap/releases) and their documentation are also available for download.


 ## Contributing

 Please read through our [contributing guidelines](https://github.com/twbs/bootstrap/blob/v3-dev/CONTRIBUTING.md). 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](https://github.com/twbs/bootstrap/tree/v3-dev/js/tests). All HTML and CSS should conform to the [Code Guide](https://github.com/mdo/code-guide), maintained by [Mark Otto](https://github.com/mdo).

 **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](https://github.com/twbs/bootstrap/tree/v4-dev), the future of the framework. Pull requests which add new features (rather than fix bugs) should target [Bootstrap v4 (the `v4-dev` git branch)](https://github.com/twbs/bootstrap/tree/v4-dev) instead.

 Editor preferences are available in the [editor config](https://github.com/twbs/bootstrap/blob/v3-dev/.editorconfig) for easy use in common text editors. Read more and download plugins at <https://editorconfig.org/>.

 ## Versioning

 For transparency into our release cycle and in striving to maintain backward compatibility, Bootstrap is maintained under [the Semantic Versioning guidelines](https://semver.org/). Sometimes we screw up, but we'll adhere to those rules whenever possible.

 See [the Releases section of our GitHub project](https://github.com/twbs/bootstrap/releases) for changelogs for each release version of Bootstrap. Release announcement posts on [the official Bootstrap blog](https://blog.getbootstrap.com/) contain summaries of the most noteworthy changes made in each release.
