 Inputs can be generated from `get_input.sh`. You will need to get your session cookie from the Advent of Code website. The easiest way to do this is to inspect any input page in your browser.
 
 The script can then be run with `bash get_input.sh SESSIONCOOKIE`, with `SESSIONCOOKIE` replaced by your unique session cookie's hash.
+
+## Usage
+
+```bash
+./advent $YEAR $DAY
+```
+
+For example, `./advent 15 1` will run Day 01 from the 2015 problems
