+# md-chips
+
+`md-chips` provides a horizontal display of (optionally) selectable, addable, and removable,
+items and an input to create additional ones (again; optional). You can read more about chips
+in the [Material Design spec](https://material.google.com/components/chips.html).
+
+This is a placeholder README for the eventual chips component.
