## Installation and Usage

Make sure you have [Julia 1.8 or newer](https://julialang.org/downloads/)
installed on your system.

### Installation

Start Julia and enter the package REPL by typing `]`. Create a new
environment:
```julia
(@v1.8) pkg> activate aoc
```

Install `AdventOfCode2023.jl`:
```
(aoc) pkg> add https://github.com/goggle/AdventOfCode2023.jl
```

Go back to the Julia REPL by pushing the `backspace` key.

### Usage

First, activate the package:
```julia
julia> using AdventOfCode2023
```

Each puzzle can now be run with `dayXY()`:
```julia
julia> day01()
2-element Vector{Int64}:
 54708
 54087
```

This will use my personal input. If you want to use another input, provide it
to the `dayXY` method as a string. You can also use the `readInput` method
to read your input from a text file:
```julia
julia> input = readInput("/path/to/input.txt")

julia> AdventOfCode2023.Day01.day01(input)
2-element Vector{Int64}:
 54708
 54087
```
