To get started, follow the “QUICK INSTRUCTIONS” found by clicking the blue Auto-Checker icon ( ) in the upper right corner of your Chrome browser window.

IF YOU DON’T SEE THE BLUE AUTO-CHECKER ICON:  The latest versions of Chrome sometimes hides extension icons underneath the puzzle piece Extensions menu-button ( ) in the upper right of the Chrome window.  When you click on the puzzle piece icon, you will then see the blue Auto-Checker icon to click on.
