+# Donors to the Godot Engine project
+
+Godot Engine is a non-profit project developed by a community of voluntary
+contributors, as well as occasional paid contributors thanks to the financial
+support of generous donors.
+
+The ways to donate to the project, as well as details on how the funds are
+used, are described on [Godot's website](https://godotengine.org/donate).
+
+The following is a list of the current monthly donors, to be have their
+generous deed immortalized in the next stable release of Godot Engine.
