 Fabric Key Assistant
 --------------------
 
-Fabric Key Assistant is a tool to help users to craft fabric key files.
+Fabric Key Assistant is a tool to help users to craft fabric key files (see details in :ref:`file_formats_fabric_key`).
 Note that crafting a fabric key is not an easy task for engineers, as its complexity grows exponentially with FPGA sizes.
 This tool is developed to assist engineers when finalizing fabric key files.
 It can apply sanity checks on hand-crafted fabric key files, helping engineers to correct and debug.
