+//! Assignment 1: Preparing for Rust Development Environment.
+//!
+//! The primary goal of this assignment is bringing up SSH, VSCode, and all the other necessary tools to develop Rust programs.
+//! Please make sure you're comfortable with developing Rust programs before moving on to the next assignments.
+//!
+//! You should fill out `add()` and `sub()` function bodies in such a way that `/scripts/grade-01.sh` works fine.
+//! See `assignment01_grade.rs` and `/scripts/grade-01.sh` for the test script.
+//!
+//! Hint: https://doc.rust-lang.org/std/primitive.usize.html
+
+/// Adds two unsigned words. If overflow happens, just wrap around.
+pub(crate) fn add(lhs: usize, rhs: usize) -> usize {
+    todo!()
+}
+
+/// Adds two unsigned words. If underflow happens, just wrap around.
+pub(crate) fn sub(lhs: usize, rhs: usize) -> usize {
+    todo!()
+}
