+ * lit-html patch to support browsers without native web components.
+ *
+ * This module should be used in addition to loading the web components
+ * polyfills via @webcomponents/webcomponentjs. When using those polyfills
+ * support for polyfilled Shadow DOM is automatic via the ShadyDOM polyfill.
+ * Scoping classes are added to DOM nodes to facilitate CSS scoping that
+ * simulates the style scoping Shadow DOM provides. ShadyDOM does this scoping
+ * to all elements added to the DOM. This module provides an important
+ * optimization for this process by pre-scoping lit-html template
+ * DOM. This means ShadyDOM does not have to scope each instance of the
+ * template DOM. Instead, each template is scoped only once.
+ *
+ * Creating scoped CSS is not covered by this module. It is, however, integrated
+ * into the lit-element and @lit/reactive-element packages. See the ShadyCSS docs
+ * for how to apply scoping to CSS:
+ * https://github.com/webcomponents/polyfills/tree/master/packages/shadycss#usage.
+ *
