If you work with Bootstrap's uncompiled source code, you need to compile the LESS files to produce usable CSS files. For LESS compilation, we only officially support Recess, which is Twitter's CSS hinter based on less.js.

Bootstrap is built to work best in the latest desktop and mobile browsers, meaning older and less advanced browsers might receive a less stylized, though fully functional, version of certain components.

Customizing Bootstrap is best accomplished when you treat it as another dependency in your development stack. Doing so ensures future upgrades are as easy as possible while also familiarizing yourself to the intricacies of the framework.
+Bootstrap is best maintained when you treat it as a separate and independently-versioned dependency in your development environment. Doing this makes upgrading Bootstrap easier in the future.
-Once you've downloaded and included Bootstrap's CSS into your templates, you can move on to customizing the included components. To do so, create a new stylesheet (LESS, if you like, or just plain CSS) to house your customizations.

Unless you plan on reading a good chunk of the compiled CSS, go with the minified. It's the same code, just compacted. Less bandwidth is good, especially in production environments.

From there, include whatever Bootstrap components and HTML content you need to get your template setup. It's best to have a rough idea in mind of modifications to make and content to include, so be sure to spend a brief amount of time on that before moving on.

You can customize components to varying degrees, but most fall into two camps: light customizations and complete visual overhauls. Luckily, plenty examples of both are available.
-We define light customizations as mostly surface layer changes, things like a color and font changes to existing Bootstrap components. A great example of this is the the Twitter Translation Center (coded by @mdo). Let's look at how to implement the custom button we wrote for this site, .btn-ttc.
Instead of using the provided Bootstrap buttons, which only require just one class to start, .btn, we'll add our own modifier class, .btn-ttc. This will give us a slightly custom look with minimal effort.

Look to the source code often and duplicate the selectors you need for your modifications. Placing them after the Bootstrap source makes for easy overriding without complication. To recap, here's the basic workflow:

For a site like Karma, which uses Bootstrap as a CSS reset with heavy modifications, more extensive work is involved, but well worth it in the end.
+Once you are comfortable performing light customizations, visual overhauls are just as straightforward. For a site like Karma, which uses Bootstrap as a CSS reset with heavy modifications, more extensive work is involved. But the same principle applies: include Bootstrap's default stylesheet first, then apply your custom stylesheet.
While not recommended for folks new to Bootstrap, you may use one of two alternate methods for customization. The first is modifying the source .less files (making upgrades super difficult), and the second is mapping source LESS code to your own classes via mixins. For the time being, neither of those options are documented here.

Not all sites and applications need to make use of everything Bootstrap has to offer, especially in production environments where bandwidth literally becomes a financial issue. We encourage folks to remove whatever is unused with our Customizer.

Using the Customizer, simply uncheck any component, feature, or asset you don't need. Hit download and swap out the default Bootstrap files with these newly customized ones. You'll get vanilla Bootstrap, but without the features *you* deem unnecessary. All custom builds include compiled and minified versions, so use whichever works for you.
