+# Advent of Code 2023
+
+## About
+
+This repository contains my solutions to the [Advent of Code 2023](https://adventofcode.com/2023) challenges using the [Rust Programming Language](https://www.rust-lang.org/) v1.74.0.
+
+To run a solution (e.g. Day 1):
+
+```sh
+cd day_1
+cargo run
+```
+
+*Note:* The solutions are not necessarily optimized for performance or readability, but rather for completing the challenge successfully.
