 # Advent Of Code
 
-> New days are generated with [`hygen`](https://github.com/jondot/hygen).
+## Getting started
->
+
-> `hygen riddle new --year 2021 --day 01`
+New "days" are generated with [`hygen`](https://github.com/jondot/hygen). This will bootstrap code for python and rust. See details about the specifica languages below
+
+```bash
+# First time setup
+bun i
+
+# Generate
+bun run gen --year 2022 --day 1
+```
+
+## Python
+
+## Rust
+
+Run a single day:
+
+```bash
+cargo run --bin 2022-01
+```
+
+Bench a day:
+
+```bash
+cargo bench --bin 2022-01
+```
+
+Bench all days:
+
+```bash
+cargo bench
+```
+
+> The benchmark is the built in Rust one. This is the [reason](https://doc.rust-lang.org/cargo/commands/cargo-bench.html) for the _nightly_ version.
