 == Specification Scope
 
+Jakarta Authentication defines a general low-level SPI for authentication mechanisms, which are controllers
+that interact with a caller and a container's environment to obtain the caller's credentials, validate these,
+and pass an authenticated identity (such as name and groups) to the container. 
+        
+Jakarta Authentication consists of several profiles, with each profile telling how a specific container
+(such as Jakarta Servlet) can integrate with- and adapt to this SPI.
