• https://donate.mozilla.org/en-US/?form=donate&utm_content=Ways_to_Give
• https://rubycentral.org/support/

Todo:

After:

• Update github funding redirection and add a global template for (new?) repos: https://docs.github.com/en/repositories/managing-your-repositorys-settings-and-features/customizing-your-repository/displaying-a-sponsor-button-in-your-repository
