+# Advent of code 2024
+
+This repository contains my solutions to the [Advent of Code 2024](https://adventofcode.com/2024) challenges
+by [Kaj](https://github.com/kws).
+
+## Running the code
+
+The code is written in Python 3.10 and uses [Poetry](https://python-poetry.org/) for dependency management.
+
+To run the code, first install Poetry and then run:
+
+```bash
+poetry install
+poetry shell
+aoc24 day<day> 
+```
+
+where `<day>` is the day number, e.g.
+
+```bash
+aoc24 day01 
+```
+
+First time you run the code you will be prompted for a username. This username
+corresponds to the subdirectory within inputs that contains your personalised inputs.
+
