+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
