A little about ko-fi
ko-fi allows you to receive income from fans of your web content. Create your button and share it anywhere on the web. Anyone who clicks your link can support you with a with a 'coffee' (a small payment that is roughly equal to the price of a coffee).
It's free to use. All you need is a PayPal account to receive payments.
Ko-fi is looking for partnerships to help expand and add value to the service. Feel free to get in touch!
