The TeachText application is a simple text editor made by Apple Computer bundled with System 7.1 and earlier. It was created by Apple programmer Bryan Stearns with later versions created by Stearns and Francis Stanbach. TeachText was one of the only applications included with the Mac system software, leading to its most frequent role as the application to open "ReadMe" files. It was named "TeachText" as a nod to its role in tutorials and other introductory materials. TeachText was derived from the Edit application, and later evolved into SimpleText.
