 ## What are Directives?
 
-At a high level, directives are instructions for AngularJS's
-{@link api/ng.$compile HTML Compiler (`$compile`)} that tell the
-compiler to attach a given behavior to a DOM node when a certain marker (such as an attribute, element
-name, or comment) appears in the DOM.
+At a high level, directives are markers on a DOM element (such as an attribute, element
+name, or CSS class) that tell AngularJS's **HTML compiler** ({@link api/ng.$compile `$compile`}) to
+attach a specified behavior to that DOM element or even transform the DOM element and its children.
 
-The process is simple. Angular comes with a set of these directives, like `ngBind`, `ngModel`, and `ngView`.
+Angular comes with a set of these directives built-in, like `ngBind`, `ngModel`, and `ngView`.
 Much like you create controllers and services, you can create your own directives for Angular to use.
-Then, when Angular {@link guide/bootstrap bootstraps}, Angular's {@link guide/compiler HTML compiler} matches
-directives against the HTML. This allows directives to register behavior or transform the DOM.
