There’s seems to be a missing video between “Download Unity & VS Code” and “IntelliSense Issues?”
The last slide in the Download video says “We’ll make sure everything works properly in next video” but the next thing is a document regarding IntelliSense Issues; the first line is… “If IntelliSense isn’t working for you in VS Code there are a simple steps you might want to try.”
That… or the “IntelliSense Issues” article needs to be moved…
