 # 🎄❄️ Advent of Sayan ⛄🔔
+
 This repository contains my codes for [Advent of Code 2023](https://adventofcode.com/2023) solutions.
 I am aiming to reach 50 stars (that is, not missing any day of AOC23).
 The solutions are majorly in python, the language I am currently most familiar with.
 The code uses pythonic/functional approaches when possible to create concise code.
 
 The reason of making this repository public is to share my solutions with others (after leaderboard is saturated).
 
+An alias I use (but not included in this repo directly) is
+
+```bash
+alias aoc='mcd $HOME/docs/projects/aoc23/$(date +%d)'
+```
+
+where `mcd` is a script to `mkdir -p` and `cd` into `$1.
+
 Merry Christmas!
