+# Advent of Code 2023
+
+I am participating in Advent of Code 2023.
+
+https://adventofcode.com/2023/
+
+Last year I dropped out on day 11, but I'm trying to complete
+it this year. My programming language of choice is Python,
+again. I haven't been programming a lot during the last
+three years, and my skills got very rusty.
+
+(No, I will not aim at the leaderboards. If I don't finish
+a problem on the same day I will finish it later.
+I will be taking my sweet time if necessary.)
