## Precompiled Bootstrap
Once downloaded, unzip the compressed folder and you'll see something like this:
```text

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](https://developers.google.com/web/tools/chrome-devtools/javascript/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/).
## CSS files
Bootstrap includes a handful of options for including some or all of our compiled CSS.
{{< bs-table "table" >}}
| CSS files | Layout | Content | Components | Utilities |
| --- | --- | --- | --- | --- |
| `bootstrap.css`
`bootstrap.min.css`
`bootstrap.rtl.css`
`bootstrap.rtl.min.css` | Included | Included | Included | Included |
| `bootstrap-grid.css`
`bootstrap-grid.rtl.css`
`bootstrap-grid.min.css`
`bootstrap-grid.rtl.min.css` | [Only grid system]({{< docsref "/layout/grid" >}}) | — | — | [Only flex utilities]({{< docsref "/utilities/flex" >}}) |
| `bootstrap-utilities.css`
`bootstrap-utilities.rtl.css`
`bootstrap-utilities.min.css`
`bootstrap-utilities.rtl.min.css` | — | — | — | Included |
| `bootstrap-reboot.css`
`bootstrap-reboot.rtl.css`
`bootstrap-reboot.min.css`
`bootstrap-reboot.rtl.min.css` | [Only Reboot]({{< docsref "/content/reboot" >}}) | — | — | [Only flex utilities]({{< docsref "/utilities/flex" >}}) |
{{< /bs-table >}}
## JS files
Similarly, we have options for including some or all of our compiled JavaScript.
{{< bs-table "table" >}}
| JS Files | Popper |
| --- | --- |
| `bootstrap.bundle.js`
`bootstrap.bundle.min.js`
| Included |
| `bootstrap.js`
`bootstrap.min.js`
| – |
{{< /bs-table >}}
## 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:
```text
bootstrap/
├── dist/
│ ├── css/
│ └── js/
├── site/
│ └──content/
│ └── docs/
│ └── {{< param 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 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.
