Summary

The documentation demonstrates a moderate Windows bias by consistently presenting Azure PowerShell (a Windows-centric tool) before Azure CLI in all code example tabs. The PowerShell sections are more detailed, with additional context and troubleshooting steps, and the documentation assumes familiarity with PowerShell cmdlets and patterns. There is no explicit mention of Linux or Bash-specific instructions, and the CLI examples, while present, are always listed after PowerShell, reinforcing a Windows-first approach. The documentation also refers to 'PowerShell' generically in some places, which may confuse cross-platform users, as PowerShell Core is available on Linux/macOS but is less commonly used than Bash.

Recommendations

Alternate the order of PowerShell and CLI examples, or present CLI (which is cross-platform) before PowerShell to avoid reinforcing a Windows-first workflow.
Explicitly mention that Azure CLI commands work natively on Linux, macOS, and Windows, and clarify that PowerShell examples are also compatible with PowerShell Core on non-Windows platforms.
Add Bash-specific notes or examples where relevant, especially for scripting scenarios.
In prerequisite sections, clarify installation instructions for both Windows and Linux environments for all tools (Azure CLI, PowerShell).
Use neutral language such as 'Azure CLI' and 'PowerShell' (with platform notes) rather than assuming a Windows environment.
Consider including troubleshooting tips or environment setup notes for Linux users, especially regarding authentication and module installation.
