To get a better feeling for what this means on the ground, let’s look at some maps.
First, the current military situation on the ground according to sources from Azerbaijan (Artsakh sources are similar):

Fig. 1 – Situational Map as of Nov. 10, 2020

There have been published a few maps that purport to show how the situation is supposed to be resolved.
The one that most closely matches the above official text is the one from Sputnik News:

Fig. 2 – Conflict Resolution Map

According to this, the green areas are already under the control of Azerbaijan. The shaded-green areas are currently under the control of Artsakh/Nagorno-Karabakh and will be handed over to Azerbaijan.
The shaded-read areas will be under the control of Russian peacekeepers, including the Lacin corridor which connects Artsakh to Armenia and the city of Shushi.

To better understand this, it is important to understand, what was the area originally covered by the Nagorno-Karabakh Oblast, this mapped is attached at the beginning of the article (the red solid line on the Fig. 2).
