TMR is a modular, open-source modification for Arma 3 aimed at increasing realism and complexity without sacrificing engaging gameplay and accessibility.
If you're looking for a download: You've come to the wrong place. Head back to the homepage: http://ryanschultz.org/tmr/
If you're a developer: TMR is licensed under the GNU GPL v2, and you're welcome to contribute with code, bug reports, and ideas.
I, Taosenai, do maintain full control of this repository though, and a submission doesn't guarantee inclusion. I have a specific vision for TMR and I will follow through on it. But you are, of course, welcome to fork TMR and maintain your own variation!
TMR uses Git to manage its code, but if you're unfamiliar with the Git VCS, you can just send your changes to me via email and I'll integrate them myself.
