 Please note that this repository is specifically for the scripts and infrastructure used to develop and build mods; bugs and feature requests against OpenRA itself should be directed to [the main OpenRA/OpenRA repository](https://github.com/OpenRA/OpenRA).  If you do come across a bug with the Mod SDK, or would like to request a new feature, then please take a look at the issue tracker first to see if it has already been reported.
 
-When developing new features, it is important to make sure that they work on all our supported platforms.  Right now, this means Windows >= 7, macOS >= 10.7, and Linux.  We would like to also support *BSD, but do not currently have a means to test this.
