+## What is Steno? Why should I use it? How do I learn?
+
+As mentioned above, steno (short for "stenography") is a shorthand, chorded
+input system that allows very fast input - licensed stenographers are required
+to type **225 WPM at 95% accuracy** to get their license.  Although reaching that
+speed typically takes 2-6 years of practice and training, lower speeds
+comparable to or exceeding that of touch typing can reportedly be reached in
+only a few months.
+
+[This talk][stenotalk] (YouTube link) gives a brief introduction to Steno, how
+it works, and why it is cool.

+
+One recommend way to get started with learning Steno is with [Plover][plover].
+Plover is software for your computer that will interpret the steno input from
+your Model 01 (or other NKRO QWERTY keyboard); it is available for Windows,
+macOS, and Linux.  Plover's [Beginner's Guide][ploverguide] is a great place to
+get started with Steno in general and Plover in particular.
