 # adventofcode2020
-Solving the 2020 edition of https://adventofcode.com/ in many languages, and test the solutions using Github CI
+Solving the 2020 edition of https://adventofcode.com/ in many languages, and test the solutions using Github CI.
+
+## Contributing
+1. Make a branch. Example: `git checkout -b jonas/day-03`
+2. Write a program, in the language of your choice. Example: `vim day-03/cmd/super-optimized.py`
+3. Test your program.
+
+```sh
+cat day-03/input | python3 day-03/cmd/super-optimized.py | diff - day-03/output
+```
+
+4. Make sure your program is automatically tested by the Github CI, by adding a line of code to `day-03/test.sh`.
+*Example line:*
+```sh
+$DIR/../scripts/test-py.sh $DIR "cmd/super-optimized.py"
+```
+
+5. Make a Pull Request to the `main` branch.
+6. Get merged!
+
+**How are programs tested?**
+
+Every program gets the `input`-challenge delivered to `stdin`, and every program is expected to answer, by writing the `output`-answer to `stdout`.
+
+```sh
+#!/bin/bash
+cat input | <run-program> | diff - output
+```
+
+**The CI does not support my favourite language. What do I do?**
+
+If we don't support the language you want to write in, don't worry. Make an issue on `Github`, and we will add it.
