-iCal4j Template provides prototypes for common iCalendar and vCard use-cases.
+iCal4j Template provides support for rendering iCalendar (and vCard) objects to other formats.
 
 ## Overview
 
-Whilst the iCalendar and vCard specifications provide generalized component and property constraints, some applications
-may require further constraints to fulfill the requirements of the use-case. iCal4j Templates provides some
-opinionated prototyping and templating for common use-cases.
+Rendering iCalendar and vCard data in UIs is a necessary feature of most calendaring applications, and this library provides
+templates to assist. Templates for individual properties or componenents may be combined to produce rendered views in various
+formats that may be used to represent objects.
 
 ## Usage
 
-iCal4j template currently provides model and view support for iCalendar and vCard prototypes. The model
-is used to create and manipulate iCalendar and vCard objects that conform with the included prototypes.
-The view provides helpers for rendering data with [Handlebars](http://jknack.github.io/handlebars.java/),

 which may be useful rendering objects in HTML or other formats.

-### Prototypes
-
-Prototyping consists of three features that may be used to create or update objects. Instantiating a
-prototype template instance supports providing an existing component instance that is used to configure
-the baseline properties and subcomponents.
-
-The template itself supports the builder pattern to configure applicable properties and subcomponents.
-
-And finally when a prototype template is applied, you can optionally supply an existing component
-instance that will be modified in-place.
-
-#### Create a default object using the meeting prototype template
-
-```java
-VEvent meeting = new Meeting().apply();
-```
-
-#### Create a meeting, using an existing event as the baseline
-
-```java
-VEvent baseline = ...
-VEvent meeting = new Meeting(baseline).apply();
-```
-
-#### Update an existing meeting to comply with the prototype
-
-```java
-VEvent existing = ...
-existing = new Meeting().apply(existing);
-```
-
-### Handlebars
-
-TBD.
