Introduction
============
-Turtle graphics is a popular way for introducing programming to kids. It was
-part of the original Logo programming language developed by Wally Feurzeig,
-Seymour Papert and Cynthia Solomon in 1967.
+Turtle graphics is an implementation of `the popular geometric drawing tools
+introduced in Logo <https://en.wikipedia.org/wiki/Turtle_
+(robot)>`_, developed by Wally Feurzeig, Seymour Papert and Cynthia Solomon
+in 1967.
+
+In Python, turtle graphics provides a representation of a physical "turtle"
+(a little robot with a pen) that draws on a sheet of paper on the floor.
+
+It's an effective and well-proven way for learners to encounter
+programming concepts and interaction with software, as it provides instant,
+visible feedback. It also provides convenient access to graphical output
+in general.
+
+Turtle drawing was originally created as an educational tool, to be used by
+teachers in the classroom. For the programmer who needs to produce some
+graphical output it can be a way to do that without the overhead of
+introducing more complex or external libraries into their work.

Imagine a robotic turtle starting at (0, 0) in the x-y plane. After an ``import turtle``, give it the
command ``turtle.forward(15)``, and it moves (on-screen!) 15 pixels in the
