| 153 | | == Licensing == |
| 154 | | |
| 155 | | The code of 0 A.D's is licensed under GPL v2 or a later version. |
| 156 | | |
| 157 | | So mods that modify this code must be licensed under a GPL v2+ compatible license. |
| 158 | | |
| 159 | | While it is situational whether newly added files count as a modification of the code of 0 A.D., |
| 160 | | if a mod copies and modifies a file of that code, it certainly is affected by the GPL. |
| 161 | | |
| 162 | | Have a quick look at our [https://code.wildfiregames.com/source/0ad/browse/ps/trunk/LICENSE.txt LICENSE.txt] file for example. |
| 163 | | 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. |
| 164 | | |
| 165 | | If you reuse or modify our art files, notice most them are licensed under a Creative Commons license and not GPL. |
| 166 | | 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. |
| 167 | | This allows other people to determine whether and how they can reuse and modify these files of your mod. |
