+setup()
+=======
+
+The ``setup()`` function is called when a sketch starts. Use it to
+initialize :ref:`variables <lang-variables>`, :ref:`pin modes
+<lang-pinmode>`, start using :ref:`libraries <libraries>`, etc. The
+``setup()`` function will only run once, after each power-up or reset
+of the Maple board.
+
+Example
+-------
+
+::
+
+ int buttonPin = 38;
+
+ void setup() {
+ pinMode(buttonPin, INPUT);
+ }
+
+ void loop() {
+ // ...
+ }
