The project is entirely **open-source** and all contributions are welcome. Feel free to maintain your own custom version, so long as the changes you make are open to the public in accordance with the GNU General Public License:
The mod is **built modularly**, so almost any included PBO can be easily removed from the configuration. This way, a team can maintain its own tailored version of ACE by simply excluding any components they don't need, or those that might possibly conflict with other add-ons. Modules themselves, e.g. the medical system, also include various customization options, allowing mission designers to tweak the overall experience.
You can help out with the ongoing development by looking for potential bugs in our code base, or by contributing new features. To contribute something to ACE, simply fork this repository and submit your pull requests for review by other collaborators. Remember to add yourself to the author array of any PBO you will be editing and the [`AUTHORS.txt`](https://github.com/acemod/ACE3/blob/master/AUTHORS.txt) file; including a valid email address.
