-Template for yearly AoC-Repositories
-
-# Usage
-
-- Clone repository (or use as template in gitea)
-- Run `pip install -r requirements.txt`
-- Update main.py and start_day.py: set YEAR (near the top) to the respective year
-- Create a file named ".session" next to your main.py containing the contents of your aoc-session cookie
-
-On a given day, just call `./start_day.py -d <day_of_month>`
-
-# Not using PyCharm?
-
-Just comment out the call() to CHARMS near the end of start_day.py
-
-# Want to add AoC-Tiles?
-
-Author: https://github.com/LiquidFun/aoc_tiles
-
-- Run `pre-commit install --hook-type post-commit`
-- In .pre-commit-config.yaml change the --overwrite-year option as needed
-- Optional: Copy your .session file to session.cookie
-- For more options see: https://github.com/LiquidFun/aoc_tiles/blob/main/aoc_tiles/config.py
-
-Tiles will be added to this README between the following lines:
-<!-- AOC TILES BEGIN -->
-<!-- AOC TILES END -->
