{:toc}
## Bootstrap CSS and JS
**Download Bootstrap's ready-to-use code to easily drop into your project.** Includes compiled and minified versions of all our CSS bundles (default, flexbox-enabled, grid only, or Reboot only) and JavaScript plugins. Doesn't include documentation or source files.

## Source files
**Want to compile Bootstrap with your project's asset pipeline?** Choose this option to download our source Sass, JavaScript, and documentation files. Requires a Sass compiler, [Autoprefixer](https://github.com/postcss/autoprefixer), [postcss-flexbugs-fixes](https://github.com/luisrudge/postcss-flexbugs-fixes), and [some setup]({{ site.baseurl }}/getting-started/build-tools/#tooling-setup).

## Bootstrap CDN
Skip the download and use the Bootstrap CDN to deliver Bootstrap's compiled CSS and JS to your project.

<script src="{{ site.cdn.js }}" integrity="{{ site.cdn.js_hash }}" crossorigin="anonymous"></script>
{% endhighlight %}
## Package managers
Pull in Bootstrap's **source files** into nearly any project with some of the most popular package managers. No matter the package manager, Bootstrap will **require a Sass compiler, [Autoprefixer](https://github.com/postcss/autoprefixer), and [postcss-flexbugs-fixes](https://github.com/luisrudge/postcss-flexbugs-fixes)** for a setup that matches our official compiled versions.
{% callout warning %}
**Heads up!** Not all package managers have the v4 alpha published yet, but we should have them up shortly!
{% endcallout %}
### npm
Install Bootstrap in your Node powered apps with [the npm package](https://www.npmjs.org/package/bootstrap):
{% highlight bash %}
npm install bootstrap@{{ site.current_version }}
{% endhighlight %}
`require('bootstrap')` will load all of Bootstrap's jQuery plugins onto the jQuery object. The `bootstrap` module itself does not export anything. You can manually load Bootstrap's jQuery plugins individually by loading the `/js/*.js` files under the package's top-level directory.
Bootstrap's `package.json` contains some additional metadata under the following keys:
- `sass` - path to Bootstrap's main [Sass](http://sass-lang.com/) source file
- `style` - path to Bootstrap's non-minified CSS that's been precompiled using the default settings (no customization)
### RubyGems
Install Bootstrap in your Ruby apps using [Bundler](https://bundler.io/) (**recommended**) and [RubyGems](https://rubygems.org/) by adding the following line to your [`Gemfile`](https://bundler.io/gemfile.html):
{% highlight ruby %}
gem 'bootstrap', '~> 4.0.0.alpha5'
{% endhighlight %}
Alternatively, if you're not using Bundler, you can install the gem by running this command:
{% highlight bash %}
gem install bootstrap -v 4.0.0.alpha5
{% endhighlight %}
[See the gem's README](https://github.com/twbs/bootstrap-rubygem/blob/master/README.md) for further details.
### Meteor
{% highlight bash %}
meteor add twbs:bootstrap@={{ site.current_version }}
{% endhighlight %}
### Composer
You can also install and manage Bootstrap's Sass and JavaScript using [Composer](https://getcomposer.org):
{% highlight bash %}
composer require twbs/bootstrap:{{ site.current_version }}
{% endhighlight %}
### Bower
Install and manage Bootstrap's Sass and JavaScript using [Bower](https://bower.io).
{% highlight bash %}
bower install bootstrap#v{{ site.current_version }}
{% endhighlight %}
### NuGet
If you develop in .NET, you can also install and manage Bootstrap's [CSS](https://www.nuget.org/packages/bootstrap/) or [Sass](https://www.nuget.org/packages/bootstrap.sass/) and JavaScript using [NuGet](https://www.nuget.org):
{% highlight powershell %}
Install-Package bootstrap -Pre
{% endhighlight %}
{% highlight powershell %}
Install-Package bootstrap.sass -Pre
{% endhighlight %}
The `-Pre` is required until Bootstrap v4 has a stable release.
