## Customizing variables
-Bootstrap 4 ships with a `_custom.scss` file for easy overriding of default variables in `/scss/_variables.scss`. Copy and paste relevant lines from there into the `_custom.scss` file, modify the values, and recompile your Sass to change our default values. **Be sure to remove the `!default` flag from override values.**
+Every Sass variable in Bootstrap 4 includes the `!default` flag, meaning you can override that default value in your own Sass even after that original variable's been defined. Copy and paste variables as needed, modify the values, remove the `!default` flag, and recompile.
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 %}
