+# Instructions
+
+Given any two lists `A` and `B`, determine if:
+
+- List `A` is equal to list `B`; or
+- List `A` contains list `B` (`A` is a superlist of `B`); or
+- List `A` is contained by list `B` (`A` is a sublist of `B`); or
+- None of the above is true, thus lists `A` and `B` are unequal
+
+Specifically, list `A` is equal to list `B` if both lists have the same values in the same order.
+List `A` is a superlist of `B` if `A` contains a contiguous sub-sequence of values equal to `B`.
+List `A` is a sublist of `B` if `B` contains a contiguous sub-sequence of values equal to `A`.
+
+Examples:
+
+- If `A = []` and `B = []` (both lists are empty), then `A` and `B` are equal
+- If `A = [1, 2, 3]` and `B = []`, then `A` is a superlist of `B`
+- If `A = []` and `B = [1, 2, 3]`, then `A` is a sublist of `B`
+- If `A = [1, 2, 3]` and `B = [1, 2, 3, 4, 5]`, then `A` is a sublist of `B`
+- If `A = [3, 4, 5]` and `B = [1, 2, 3, 4, 5]`, then `A` is a sublist of `B`
+- If `A = [3, 4]` and `B = [1, 2, 3, 4, 5]`, then `A` is a sublist of `B`
+- If `A = [1, 2, 3]` and `B = [1, 2, 3]`, then `A` and `B` are equal
+- If `A = [1, 2, 3, 4, 5]` and `B = [2, 3, 4]`, then `A` is a superlist of `B`
+- If `A = [1, 2, 4]` and `B = [1, 2, 3, 4, 5]`, then `A` and `B` are unequal
+- If `A = [1, 2, 3]` and `B = [1, 3, 2]`, then `A` and `B` are unequal
