Discover what’s included in Bootstrap, including our precompiled and source code flavors. Remember, Bootstrap’s JavaScript plugins require jQuery.

## Precompiled Bootstrap

Once downloaded, unzip the compressed folder and you’ll see something like this:

    bootstrap/
    ├── css/
    │   ├── bootstrap-grid.css
    │   ├── bootstrap-grid.css.map
    │   ├── bootstrap-grid.min.css
    │   ├── bootstrap-grid.min.css.map
    │   ├── bootstrap-reboot.css
    │   ├── bootstrap-reboot.css.map
    │   ├── bootstrap-reboot.min.css
    │   ├── bootstrap-reboot.min.css.map
    │   ├── bootstrap.css
    │   ├── bootstrap.css.map
    │   ├── bootstrap.min.css
    │   └── bootstrap.min.css.map
    └── js/
        ├── bootstrap.bundle.js
        ├── bootstrap.bundle.js.map
        ├── bootstrap.bundle.min.js
        ├── bootstrap.bundle.min.js.map
        ├── bootstrap.js
        ├── bootstrap.js.map
        ├── bootstrap.min.js
        └── bootstrap.min.js.map

This is the most basic form of Bootstrap: precompiled files for quick drop-in usage in nearly any web project. We provide compiled CSS and JS (`bootstrap.*`), as well as compiled and minified CSS and JS (`bootstrap.min.*`). source maps (`bootstrap.*.map`) are available for use with certain browsers’ developer tools. Bundled JS files (`bootstrap.bundle.js` and minified `bootstrap.bundle.min.js`) include Popper, but not jQuery.

## CSS files

Bootstrap includes a handful of options for including some or all of our compiled CSS.

CSS files | Layout | Content | Components | Utilities
--- | --- | --- | --- | ---
`bootstrap.css` `bootstrap.min.css` | Included | Included | Included | Included
`bootstrap-grid.css` `bootstrap-grid.min.css` | Only grid system | Not included | Not included | Only flex utilities
`bootstrap-reboot.css` `bootstrap-reboot.min.css` | Not included | Only Reboot | Not included | Not included

## JS files

Similarly, we have options for including some or all of our compiled JavaScript.

JS files | Popper | jQuery
--- | --- | ---
`bootstrap.bundle.js` `bootstrap.bundle.min.js` | Included | Not included
`bootstrap.js` `bootstrap.min.js` | Not included | Not included

## Bootstrap source code

The Bootstrap source code download includes the precompiled CSS and JavaScript assets, along with source Sass, JavaScript, and documentation. More specifically, it includes the following and more:

    bootstrap/
    ├── dist/
    │   ├── css/
    │   └── js/
    ├── docs/
    │   └── examples/
    ├── js/
    └── scss/

The `scss/` and `js/` are the source code for our CSS and JavaScript. The `dist/` folder includes everything listed in the precompiled download section above. The `docs/` folder includes the source code for our documentation, and `examples/` of Bootstrap usage. Beyond that, any other included file provides support for packages, license information, and development.
