Summary

The documentation provides only a PowerShell script for automating VM deletion, with no equivalent Bash, Azure CLI, or Linux-friendly example. The automation section is Windows/PowerShell-centric, and there is no mention of cross-platform tools or alternatives for Linux/macOS users.

Recommendations

Add an Azure CLI (az) example for deleting all VMs in a lab, as Azure CLI is cross-platform and commonly used on Linux/macOS.
Include Bash script examples or instructions for Linux users where automation is discussed.
Explicitly mention that PowerShell Core is cross-platform if recommending PowerShell, and provide installation guidance for non-Windows systems.
Ensure that any automation or scripting guidance is presented with parity for both Windows and Linux users, ideally showing both PowerShell and CLI/Bash alternatives side by side.
