I suggest adding license information to encourage open source contributions.

Which license should I go with?

I welcome anyone to do whatever they wish with the code

Do I go with the MIT one?

In this case a short and permissive MIT license seems to be a good choice.
This guide outlines how to use license templates: https://docs.github.com/en/communities/setting-up-your-project-for-healthy-contributions/adding-a-license-to-a-repository
