Missing donation info in README.md

[buhtz]

Please add donation info in your README.md file.

I am aware that there is a "donation" button in regex101.com. But Is is not a link. It is a drop down menu with two sub links.

My intention is to link to your projects donation options from my own README because I don't accept donations but would like to redirect to other projects.

EDIT:
And by the way, both offered options (PayPal and Microsoft GitHub) are worth discussion because they have ethical issues. Despite the value of your work for my own work I don't feel well offering PayPal and GH links to my users.

What is your product? What do you propose as an ethical alternative?

I don't collect donations in my project. That is why I redirect my users to other projects my project depends on.

I often read about https://liberapay.com (also used by GNU) and https://www.patreon.com/. Others I could found are https://coindrop.to/ and https://www.buymeacoffee.com/.

Just out of interest: May I ask how much you get on donations and how you use it?
