 Zope Component Architecture with PyAMS
 ++++++++++++++++++++++++++++++++++++++
 
-The **Zope Component Architecture** (aka **ZCA**) is used by the Pyramid framework "under the hood" to handle interfaces,

+PyAMS packages are developed based on the **Zope Component Architecture** (aka **ZCA**). ZCA is used by the Pyramid framework
+"under the hood" to handle interfaces, adapters and utilities. You don't **have to** use it in your own applications.
+But you can.
 
 The ZCA is mainly adding elements like **interfaces**, **adapters** and **utilities** to the Python language. It
 allows you to write a framework or an application by using **components** which can be extended easily.
