How exactly did Hindenburg and Ludendorff take power from the Kaiser during WW1? Were there any defining events, or was it more of a gradual shift?

Follow up question: was the German public aware of Hindenburg and Ludendorff's increased control over the government, or was it mostly hidden from them. If they did know, did the German people accept their authority or was there public backlash against it?
