Summary
The documentation is heavily biased toward Windows and PowerShell usage. All examples use PowerShell cmdlets, Windows file paths (e.g., C:\), and Windows-centric tools and workflows. Linux is only mentioned in passing, with no Bash, Azure CLI, or Linux-native examples provided. The documentation assumes the user is operating in a Windows environment, even for Linux VM scenarios.
Recommendations
- Provide equivalent Azure CLI and Bash examples for all PowerShell commands, especially for Linux users.
- Use platform-agnostic file paths or provide both Windows (C:\) and Linux (/home/user/) path examples.
- Include explicit instructions for restoring keys and secrets from Linux or macOS environments, not just Windows.
- Mention and demonstrate cross-platform tools (e.g., Azure CLI, REST API) alongside PowerShell.
- Reorder sections or examples so that Linux and Windows are given equal prominence, or clarify when steps are identical across platforms.
