First off, thank you for considering contributing to PokéTrivia.
If you've noticed a bug or have a feature request, make sure to check our issues if there's something similar to what you've observed or want to suggest. If there isn't, feel free to open a new issue!
If this is something you think you can fix, then fork the repository and create a branch with a descriptive name.
A good branch name would be (where issue #107 is the ticket you're working on):
git checkout -b feature/107-add-socketsio
