+## Structure
+
+Every solution is grouped by its year and day and (usually) consists of five files:
+
+| Filename                            | Purpose                                                                                                 |
+| ----------------------------------- | ------------------------------------------------------------------------------------------------------- |
+| `<year>/<day>/index.ts`             | Has the solution. Exports two functions: `solveFirst(string): number` and `solveSecond(string): number` |
+| `<year>/<day>/index.test.ts`        | Unit test using the example input and expected solution.                                                |
+| `<year>/<day>/run.ts`               | Basic run script: Loading the actual input and passing it into the two solve functions.                 |
+| `<year>/<day>/input.txt`            | Input text from AOC.                                                                                    |
+| `<year>/<day>/<year>-<day>.run.xml` | IntelliJ/Webstorm runfile for `run.ts` using Bun.                                                       |

+To run a single day, first copy your input file from `https://adventofcode.com/<year>/day/<day>/input` into
+`<year>/<day>/input.txt`. Then run:
