Screen record a video with Quicktime player if you have a Macbook.
Don't do more than 10 seconds per GiF because it isn't useful.
Make sure to turn off "Show Mouse Clicks"
When recording a small part of the screen, make sure to ZOOM in on Chrome and record a blown-up portion of the Gif area. If you record a small area without zooming in, the gif will be very low quality.
