Setting up ignition timing on M117.984

I recondition distributor on my car and reinstalling it, one problem is that I have no idea how to tune the ignition timing. Is there a step by step guide on how to do it? I got all the tools and data just don't know the procedure.

For my car the setting should be:

Adjusting Value of Firing Point with vacuum at idle: 5 degrees TDC
Test values ignition adjustment with vacuum @ 1500rpm: 11-15 degrees
Test values ignition adjustment with vacuum @ 3000rpm: 18-22 degrees
Vacuum adjustment after retard at idle: 10-14 degrees
Installation value of ignition distributor at starting speed without vacuum: 7 degrees before TDC

Can anyone point out to a DIY that explains how to apply that data? I searched on this forum and googled and surprisingly found nothing.
