First of all, thank you for taking some time to contribute to the project ! 👍
Please read the code of conduct before starting anything.
Then, you can find the project documentation here. Everything is explained in details in here, so please read it once before asking questions.
If you found a bug or a typo, you should search if your problem was already stated on a closed issue first. Sometimes the "bug" is not one at all. If not, please fill an issue.
