The document provides an overview of the vi and vim text editors, including their history, features, and how to work efficiently using modes, motions, and commands. Vi was originally created in 1976 and vim was created in 1991 as an improved version of vi with more features while retaining compatibility. The overview explains why vim is useful to learn, how to navigate and edit text using modes, and examples of common commands like substitutions and plugins.

1. You press the keys with no effect,
Your mode is not correct.
The screen blurs, your fingers shake;
You forgot to press escape.
Can't insert, can't delete,
Cursor keys won't repeat.
You try to quit, but can't leave,
An extra "bang" is all you need.
