You make some good points.
Significantly the version 8 software is under heavy development right now, with it eventually superseding the current version 7 software. As it is undergoing constant change threads such as these do become obsolete, and serve to potentially provide no longer accurate information to users. For instance, it is no longer really necessary (in the main) to modify the Options.txt file manually. This activity is performed no through the version 8 Scan and Tune application.
As we get closer to the complete release of version 8 there will clearly be documentation produced and updated tutorials.
