+# Advent of Code 2022
+This Repository contains my solutions for the [Advent of Code 2022](https://adventofcode.com/2022).
+
+## Execute Solutions
+(Make sure you have [Deno](https://deno.land) installed.)
+To run the code for a given day just run the existing task for it.
+For example to run the code for the first day run `deno task Day01`.
