 // Rust-101, Part 00
 // =================
 
+// As a starter, we want to write a function that computes the minimum of a list.
+// First, we need to get a list. For now, let's just hard-code some sample list.
+// Later, we will ask the user to input a list.
+// 
+// Observe how in Rust, the function type comes *after* the arguments (which, in
+// this case, the function does not have). `Vec<i32>` is the type of a growable list
+// of (signed, 32-bit) integers.
 
 pub fn read_vec() -> Vec<i32> {
     vec![0,1,2,3,4]
