+* See `aoc2020.day1` for an example. If a solution is worth an explanation, it should go to the description in the docs in `dayN-docs.factor`.
 * By convention, the `MAIN:` function solves the exact task given, while the core function solves the core problem (no input parsing, no output formatting). Sometimes it solves a more generalized problem; sometimes it solves only a specific subset of the problem (which happens in AoC problems, when an input exploit is needed).
+* `dayN-tests.factor` should contain the test cases for the puzzle. It may be a good idea to start with the model problem and solution for that day. Later, you can incorporate your personal dataset, which is kept in `datasets/aoc2020/dayN.txt`.
