-## Perform baseline testing
+## Overview
 
-You can perform baseline testing of Rust on GCP SUSE aarch64 VMs to verify installation, build functionality, and compilation performance on the Arm-based Axion C4A platform.
+Now that Rust is installed, verify the installation, build functionality, and compilation performance on your Arm-based Axion C4A instance.

 The timing results show that Rust compilation performs well on the Arm64 architecture, with the "real" time indicating the total elapsed time for the build process.

+## What you've accomplished and what's next

+You've successfully verified your Rust installation and measured baseline compilation performance on the C4A instance. In the next section, you'll benchmark Rust code execution using Criterion to measure runtime performance and consistency.
