+# Advent of Code 2020
+
+## Completion
+
+Days 6 and 12 are missing because I did them in IPython and never bothered putting them in a source file, probably.

+## Benchmarks (Rust)
+
+I'm somewhat trying to do the <1 second challenge, but I've been a bit short on time (and willpower), and I'm just faster at solving challenges in Python. Anyway, here's my benchmarks (ran on my mostly idle server):
