Clone this repository or download the zip, then run the p5 Editor. In the p5 Editor, click File > Open and navigate to cv-examples/ and select index.html. Click the play button, and this should launch the browser with links to each of the sketches.
If you run one of the sketches by itself, it might not work because it is including some functions from ../shared/utils.js.
