+# Arrays
+
+Arrays in Limbo are dynamic and indexed by 0. They can be initialized providing a size, or declared and initialized in two separate statements if no size is specified. 
+
+Disclaimer: I don't like this example very much, but I'm not sure how to shore it up. The less on here is to use lists.

+## Exercises
+
+- Play with the widths of different arrays, what happens?
+- What can you initialize with the `* =>` operator, what can't you?
