const gest = new Gestate({debug: true})
gest.record(MyHTMLElement, 'gesture type', offsetTime)
gest.stopRecording()
gest.getGestures()
gest.clear()

Basic operation notes

Gestate creates a canvas element under the BODY element. When record() is called, the canvas is resized to cover the HTMLElement argument. The canvas captures mouse events and renders the particle effects.
