 ## FAQ about contributing
 
-### Where can I write my question and remarks?
+### What license does my code need to be under?
 
-We use [GitHub's issue tracker](https://github.com/littlevgl/lvgl/issues) to ask questions., report bugs and suggest features. But there are some simple rules:
+Any code added to LittlevGL must be licensed under [MIT](https://choosealicense.com/licenses/mit/) or another license that is fully compatible. Contributions under other licenses are highly likely to be rejected.
+
+If you borrow code from another project, please make sure to add their copyright notice to your contribution.
