 # Lab 3 — Memory Diagrams, Testing, and Debugging
 
+For this lab, you must use a termial. Do not use IDEs for this lab.
+
 ## Checkpoint 1
 *estimate: 20-40 minutes*
 
+Read lecture notes [5.7](../../lectures/05_pointers#57-arrays) and [5.8](../../lectures/05_pointers#58-stepping-through-arrays-with-pointers-array-iterators), and try to understand the example code and run the animations. Ask questions if you don't understand the code.
+
 Write a function compute_squares that takes 3 arguments: two C-style arrays (not STL vectors), a and b,
 of unsigned integers, and an unsigned integer, n, representing the size of each of the arrays. The function
 should square each element in the first array, a, and write each result into the corresponding slot in the second
