Summary

The documentation page demonstrates a moderate Windows bias. Windows-specific tools (IISNode, web.config) and troubleshooting steps are described in detail, while their Linux equivalents are either omitted or referenced less prominently. Windows instructions and examples often appear before Linux ones, and PowerShell is mentioned for Application Insights instrumentation, with no Linux CLI or Bash alternative. Some sections (e.g., troubleshooting, web.config) are Windows-only, with Linux equivalents missing or relegated to includes. The overall structure and depth of Windows content exceeds that of Linux.

Recommendations

Ensure Linux instructions/examples are presented with equal prominence and detail as Windows, including troubleshooting and configuration steps.
Provide Linux/Bash alternatives for PowerShell instructions, especially for instrumentation and automation tasks.
Include explicit Linux equivalents for Windows-specific tools (e.g., IISNode, web.config), or clarify when they are not needed on Linux.
Avoid presenting Windows instructions before Linux ones; use parallel structure or combine where possible.
Expand Linux troubleshooting guidance to match the detail provided for Windows.
Where platform-specific includes are used, summarize their content or link to them directly for parity.
