+# Advent of Code 2022
+
+I did not solve these problems in 2022, but in 2025, as a playground
+to learn Rust.
+
+## Usage
+
+To run this code you'll need the `rustc` compiler (no `cargo`).
+
+From this folder run: `./run.sh day part`, for example `./run.sh 03 a`.
+Input is read from standard input; paste your input in the terminal or
+read it from a file with e.g. `<input.txt`.
