## Compiled Bootstrap

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

{/* NOTE: This info is intentionally duplicated in the README. Copy any changes made here over to the README too, but be sure to keep in mind to add the `dist` folder. */}

This is the most basic form of Bootstrap: compiled 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](https://web.dev/articles/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](https://popper.js.org/docs/v2/).

### CSS files

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

<BsTable class="table">
| CSS files | Layout | Content | Components | Utilities |
| --- | --- | --- | --- | --- |
| `bootstrap.css`<br/> `bootstrap.min.css`<br/> `bootstrap.rtl.css`<br/> `bootstrap.rtl.min.css` | Included | Included | Included | Included |
| `bootstrap-grid.css`<br/> `bootstrap-grid.rtl.css`<br/> `bootstrap-grid.min.css`<br/> `bootstrap-grid.rtl.min.css` | [Only grid system]([[docsref:/layout/grid]]) | — | — | [Only flex utilities]([[docsref:/utilities/flex]]) |
| `bootstrap-utilities.css`<br/> `bootstrap-utilities.rtl.css`<br/> `bootstrap-utilities.min.css`<br/> `bootstrap-utilities.rtl.min.css` | — | — | — | Included |
| `bootstrap-reboot.css`<br/> `bootstrap-reboot.rtl.css`<br/> `bootstrap-reboot.min.css`<br/> `bootstrap-reboot.rtl.min.css` | — | [Only Reboot]([[docsref:/content/reboot]]) | — | — |
</BsTable>

### JS files

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

<BsTable class="table">
| JS Files | Popper |
| --- | --- |
| `bootstrap.bundle.js`<br/> `bootstrap.bundle.min.js`<br/> | Included |
| `bootstrap.js`<br/> `bootstrap.min.js`<br/> | – |
</BsTable>

## Bootstrap source code

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

```text
bootstrap/
├── dist/
│   ├── css/
│   └── js/
├── site/
│   └──content/
│      └── docs/
│          └── [[config:docs_version]]/
│              └── examples/
├── js/
└── scss/
```

The `scss/` and `js/` are the source code for our CSS and JavaScript. The `dist/` folder includes everything listed in the compiled download section above. The `site/content/docs/` folder includes the source code for our hosted documentation, including our live examples of Bootstrap usage.

Beyond that, any other included file provides support for packages, license information, and development.
