+This repository contains my attempt to solve the 2022 edition of the [Advent of Code](https://adventofcode.com/2022)
+challenge using Perl 5.
+
+Note: For this set of puzzles, I decided to read the entire input file into a scalar variable (i.e. slurp the file).
+To do this, you'll see the following near the beginning of each file:
+
+ chomp( my $input = do { local $/; <> } );
+
+More information regarding this syntax can be found here:
+https://www.perl.com/article/21/2013/4/21/Read-an-entire-file-into-a-string/
