+### Leading and Trailing Icons
 
 You can optionally add a leading icon (i.e. thumbnail) and/or a trailing icon to a chip. To add an icon, add an `i` element with your preferred icon, give it a class of `mdc-chip__icon`, and a class of either `mdc-chip__icon--leading` or `mdc-chip__icon--trailing`. If you're adding a trailing icon, also set `tabindex="0"` and `role="button"` to make it accessible by keyboard and screenreader.

+Choice chips are a variant of chips which allow single selection from a set of options. To define a set of chips as choice chips, add the class `mdc-chip-set--choice` to the chip set element.

-Filter chips are a variant of chips which allow multiple selection from a set of options. When a filter chip is selected, a checkmark appears as the leading icon. If the chip already has a leading icon, the checkmark replaces it. This requires the HTML structure of a filter chip to differ from other chips:

You'd also want to add an event listener that calls `addChip` on the `MDCChipSet` to convert text to a chip. More information can be found in the "`MDCChip` Properties and Methods" section below.

 The MDC Chips module is comprised of two JavaScript classes:
-* `MDCChip` defines the behavior of a single chip
+* `MDCChip` defines the behavior of a single chip.
 * `MDCChipSet` defines the behavior of chips within a specific set. For example, chips in an input chip set behave differently from those in a filter chip set.
 
 To use the `MDCChip` and `MDCChipSet` classes, [import](../../docs/importing-js.md) both classes from `@material/chips`.

+## Usage within Web Frameworks
+
+If you are using a JavaScript framework, such as React or Angular, you can create a <COMPONENT_NAME> for your framework. Depending on your needs, you can use the _Simple Approach: Wrapping MDC Web Vanilla Components_, or the _Advanced Approach: Using Foundations and Adapters_. Please follow the instructions [here](../integrating-into-frameworks.md).
