+## Styling utilities
+The CDK `a11y` package comes with a set of CSS styles that can be used when building accessible
+components. To take advantage of them, you have to include the styles in your global stylesheet.
+If you're using Material together with the CDK, these styles have been included for you already.
+
+```scss
+@import '~@angular/cdk/text-field/text-field';
+
+@include cdk-a11y();
+```
+
+### Hiding elements, while keeping them available for screen readers
+By default, screen readers and other assistive technology will skip elements that have
+`display: none`, `visibility: hidden` etc. In some cases you may need to visually hide an element,
+while keeping it available for assistive technology. You can do so using the `cdk-visually-hidden`
+class:
+
+```html
+<div class="custom-checkbox">
+  <input type="checkbox" class="cdk-visually-hidden">
+</div>
+```
+
+### Targeting high contrast users
+The `a11y` package offers a mixin that allows you to target users that have the Windows high
+contrast mode turned on, via a media query. To target high contrast users, you can wrap your
+styles with the `cdk-high-contrast` mixin:
+
+```scss
+button {
+  @include cdk-high-contrast {
+    outline: solid 1px;
+  }
+}
+```
