## Precompiled Bootstrap

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

                    bootstrap/
                    ├── css/
                    │   ├── bootstrap-grid.css

                        ├── bootstrap.esm.js.map
                        ├── bootstrap.esm.min.js
                        ├── bootstrap.esm.min.js.map

                        └── 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.

## 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 | — | — | Only flex utilities
`bootstrap-utilities.css` `bootstrap-utilities.min.css` | — | — | — | Included
`bootstrap-reboot.css` `bootstrap-reboot.min.css` | — | Only Reboot | — | —

## JS files

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

JS files | Popper
--- | ---
`bootstrap.bundle.js` `bootstrap.bundle.min.js` | Included
`bootstrap.js` `bootstrap.min.js` | —

## 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/
                    ├── site/
                    │   └──content/
                    │      └── docs/
                    │          └── 5.0/
                    │              └── 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 `site/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.
