 You may want to publish your mod on the [https://mod.io mod.io platform]. If you do so, your mod will be available in the 0 A.D. mod downloader. To avoid security issues, we take some extra validation steps: follow [https://wildfiregames.com/forum/index.php?/topic/24333-guide-for-publishing-mods-on-modio/ the guide on the forums].
  
-== Legal notice: Because 0AD's code is written under GPL 2 license mods must be under the GPL 2 license and above or otherwise if the code is licensed differently ==
+== Licensing ==
+
+The code of 0 A.D's is licensed under GPL v2 or a later version.
+
+So mods that modify this code must be licensed under a GPL v2+ compatible license.
+
+While it is situational whether newly added files count as a modification of the code of 0 A.D.,
+if a mod copies and modifies a file of that code, it certainly is affected by the GPL.
+
+Have a quick look at our [https://code.wildfiregames.com/source/0ad/browse/ps/trunk/LICENSE.txt LICENSE.txt] file for example.
+Add a custom `LICENSE.txt` to your mod folder to explain the licensing when redistributing the mod and list all copyright holders whose work you have reused.
+
+If you reuse or modify our art files, notice most them are licensed under a Creative Commons license and not GPL.
+If you distribute copies or modifications of other peoples art files, make sure you have permission to do so and mention the terms of the permission in the license file.
+This allows other people to determine whether and how they can reuse and modify these files of your mod.
