**System requirements:** - 2.4 GHz CPU or faster (multi-core recommended) - Windows 7, 8 or 10 - Graphics card with OpenGL 3.2 support **Required software on Windows:** - [Microsoft .Net Framework 4.7.2](https://dotnet.microsoft.com/download/dotnet-framework/net472) **Building on Linux:** - Install mono. On debian based distros `apt-get install mono-complete` should do the trick - Install gcc - Type `make`. If you get an error about it not finding `msbuild` then you are most likely missing a package, or your version of mono may be too old - Run it by launching `builder` from inside the Build folder **Links:** - [Official thread link](https://forum.zdoom.org/viewtopic.php?f=232&t=66745) - [Git builds at DRDTeam.org](https://devbuilds.drdteam.org/ultimatedoombuilder/) More detailed info can be found in the **editor documentation** (Refmanual.chm)
