+Firmware Framework for Armv8-A
+==============================
+
+|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."*
+
+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.
