-With Bootstrap 4, we've added a handful of global options for easily customizing all the components in your project. These options are handled by Sass variables. Simply change a variable's value and recompile with the included Gruntfile.
+Customize Bootstrap 4 with our built-in custom variables file and easily toggle global CSS preferences with new `$enable-*` Sass variables. Override a variable's value and recompile with the included Gruntfile as needed.
-## Available variables
+## Customizing variables
-You can find and customize these variables in our `_variables.scss` file.
+Bootstrap 4 ships with a `_custom.scss` file for easy variable overrides. Copy and paste relevant lines from `_variables.scss` into the custom file and recompile your Sass to change our default values. **Be sure to remove the `!default` flag from override values.**
+
+For example, to change out the `background-color` and `color` for the `<body>`, you'd do the following:
+
+{% highlight scss %}
+// Bootstrap overrides
+//
+// Copy variables from `_variables.scss` to this file to override default values
+// without modifying source files.
+
+$body-bg: $gray-dark;
+$body-color: $gray-light;
+{% endhighlight %}
+
+Do the same for any variable you need to override, including the global options listed below.
+
+## Global options
+
+You can find and customize these variables for key global options in our `_variables.scss` file.
| Variable | Values | Description |
| --------------------------- | ---------------------------------- | ----------------------------------------------------------------------- |
-// Custom Overrides
+// Bootstrap overrides
//
-// Copy settings from `_variables.scss` to this file to override
-// the Bootstrap defaults without modifying key, versioned files.
+// Copy variables from `_variables.scss` to this file to override default values
