+## Precompiled 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. -->
+
+{% highlight plaintext %}
+bootstrap/
+├── css/
+│   ├── bootstrap.css
+│   ├── bootstrap.css.map
+│   ├── bootstrap.min.css
+│   └── bootstrap.min.css.map
+└── js/
+    ├── bootstrap.js
+    └── bootstrap.min.js
+{% endhighlight %}
+
+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.*`). CSS [source maps](https://developers.google.com/web/tools/chrome-devtools/javascript/source-maps) (`bootstrap.*.map`) are available for use with certain browsers' developer tools.
+
+## 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:
+
+{% highlight plaintext %}
+bootstrap/
+├── dist/
+│   ├── css/
+│   └── js/
+├── docs/
+│   └── examples/
+├── js/
+└── scss/
+{% endhighlight %}
+
+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.
