+who_is_this_for: This is an advanced topic for performance engineers looking for ways to increase performance on Arm servers.
 
 learning_objectives:
-    - enable libhugetlbfs to increase performance
-    - see how much performance improved on workloads like MySQL, Redis.
+    - Enable libhugetlbfs on an Arm server running Linux
+    - Evaluate performance improvements for workloads such as MySQL.
 
 prerequisites:
-    - system with ubuntu 20 installed
-    - knowledge to build MySQL server, and run sysbench benchmark test
-    - knowledge to build Redis server, and run memtier benchmark test
+    - An Arm server or virtual machine instance from a cloud service provider with Ubuntu installed
+    - Knowledge to build MySQL server and run the sysbench benchmark test
