Add a new amount at the check-out

Hi guys,

First, I wanna thank you for the time you are taking reading me ??

Then, my question is that I wanna add a charity donation but I have no idea how to do it with Woocomerce.
The best would be that this donation would be an option for the customer. For example : “tick this point to make 1€ donation” OR “tick this point and insert the amount you wanna donate to Indonesia charity project”. And of course, I’d like to add a comment explaining what it is for (even if it is explained on the website, it would be better to remind it there).

I hope it is possible and you will help me ??

Thank you so much and good continuation to everyone !!

Marc
