Yes, I think we should remove it as part of #480. Thanks.

Best Regards,

Yonghong,

The sentence about setting a PCD from the command line is related to

https://bugzilla.tianocore.org/show_bug.cgi?id=480

#480 Build spec: add description for Override PCD value on the command line

This will update the Build Specification to add the --pcd command line flag to set PCD values. 

Should the following item be removed as part of #480?

" 5. Command > line cannot be used to set the PCD value."

Thanks,

Mike
