+who_is_this_for: This is an introductory topic for developers and performance engineers who want to characterize the hardware performance of Arm-based Linux systems using Arm Performix.
 
 learning_objectives:
     - Run Arm Performix's System Characterization recipe to understand hardware configuration and performance
     - Interpret memory latency and bandwidth benchmark results
-    - View the output directory to inspect generated plots and raw results
+    - Locate and interpret the generated plots and raw benchmark data in the output directory
 
 prerequisites:
-    - A target machine to benchmark. The Arm System Characterization Tool, included with Performix, is cross-platform and cross-OS.
+    - A Arm Linux target machine accessible via SSH to characterize.
