 Firmware Framework for Armv8-A
 ==============================
+The |FF-A| specification defines a software architecture that isolates Secure world firmware images from each other. The
+specification defines interfaces that standardize communication between various images. This includes communication
+between images in the Secure world and Normal world.
 
-|FF-A| is a standard which *"describes interfaces that standardize communication between the various software images. This
-includes communication between images in the Secure world and Normal world."*
+The Trusted Services project includes service providers that may be deployed within FF-A S-EL0 secure partitions. This
+includes service providers that form the security foundations needed for meeting PSA Certified requirements. Other secure
+partitions are available such as the SMM Gateway to provide Secure world backing for UEFI services.
 
-Trusted Services is the home of the FF-A S-EL0 Secure Partitions implementing PSA functionality. The component :ref:`libsp`
-captures helpful abstractions to allow easy FF-A compliant S-EL0 SP development. S-EL0 SPs are SPMC agonistic and can be used
-with an SPMC running in any higher secure exception level (S-EL1 - S-EL3). Currently the solution is tested with an SPMC
-running at S-SEL1 integrated into OP-TEE OS.
