+If LVGL saved you a lot of time and money or you just had fun using it, consider [Supporting its Development](https://opencollective.com/lvgl).
+
+**How do we spend the donations?**<br>
+Our goal is to provide financial compensation for people who do the most for LVGL. It means not only the maintainers but anyone who implements a great feature should get a payment from the accumulated money. We use the donations to cover our operational costs like servers and related services.
+
+**How to donate?**<br>
+We use [Open Collective](https://opencollective.com/lvgl) where you can easily send one time or recurring donations. You can also see all of our expenses  in a transparent way. 
+
+**How to get paid for your contribution?**<br>
+If someone implements or fixes an issue labeled as [Sponsored](https://github.com/lvgl/lvgl/labels/Sponsored) he or she will get a payment for that work. We estimate the required time, complexity and importance of the issue and set a price accordingly. To jump in just comment on a [Sponsored](https://github.com/lvgl/lvgl/labels/Sponsored) issue saying *"Hi, I'd like to deal with it. This is how I'm planning to fix/implement it...". A work is considered ready when it's approved and merged by a maintainer. After that you can submit and expense at [opencollective.com](https://opencollective.com/lvgl) and you payment will be sent in a few days.
