+We accept pull requests which will undergo a review of at least 1 of this project's contributors. These will be checked for validity of both, correctness and coding standards. If an issue will arise, you will be informed with a detailed explanation of what changes are needed in order for your pull request to be included in the project.

+Please **do NOT** submit pull requests with translations directly inside the code. You can create new language constants in the [`GameEngine/Lang/en.php`](https://github.com/Shadowss/TravianZ/tree/master/GameEngine/Lang) file + your own language file respectively, then use these everywhere in the code.
+
+If you would like to transfer your knowledge about Travian, including gameplay, mathematical equations used to calculate things inside or strategies, please don't hesitate to contribute either directly to [our Wiki](https://github.com/Shadowss/TravianZ/wiki) (if you have permissions) or by creating a new issue / pull request.
