Summary
The documentation provides both Linux and Windows (specifically EFLOW) instructions, but the Windows/PowerShell tooling is emphasized for EFLOW scenarios. Several steps for EFLOW require the use of custom PowerShell cmdlets (e.g., Copy-EflowVMFile, Connect-EflowVm, Invoke-EflowVmCommand), and these tools are referenced before or instead of standard cross-platform alternatives. The Linux path uses standard Bash commands, while the Windows/EFLOW path assumes the user is operating from a Windows host using PowerShell, potentially limiting accessibility for users on non-Windows platforms. There is also a slight 'windows_first' bias in the EFLOW sections, where Windows-specific instructions and tools are introduced before cross-platform or Linux-native alternatives.
Recommendations
- Where possible, provide cross-platform alternatives to PowerShell cmdlets for EFLOW, such as using SSH/SCP from Linux/macOS hosts to the EFLOW VM.
- Clarify that EFLOW is a Windows-specific scenario, but highlight how similar tasks can be accomplished from non-Windows hosts if possible.
- In the EFLOW sections, mention standard Linux tools (e.g., scp, ssh) as alternatives to PowerShell cmdlets for copying files and executing commands, or explain any limitations.
- Ensure that Linux and Windows instructions are presented with equal prominence and detail, and avoid assuming the user is operating from a Windows host when working with EFLOW.
- Consider adding a table or section summarizing all possible ways (Windows/PowerShell, Linux/SSH, etc.) to interact with the EFLOW VM for certificate management and port configuration.
