On a video made by Elektor, I saw they were able to put the Schematic on the silkscreen of the PCB.

For the same kind of didactic purpose, I’m interested to understand how to do it.
I asked in the comments of the video, but I didn’t get any feedback yet, so I ask here, perhaps there is somebody was able to do the same.
