**System requirements:** - 2.4 GHz CPU or faster (multi-core recommended) - Windows 7 or above - 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:** These instructions are for Debian-based distros and were tested with Debian 10 and Ubuntu 18.04. For others it should be similar. __Note:__ this is experimental. None of the developers are using Linux as a desktop OS, so you're pretty much on your own if you encounter any problems with running the application. - Install Mono. The `mono-complete` package from the Debian repo doesn't include `msbuild`, so you have to install `mono-complete` by following the instructions on the Mono project's website: https://www.mono-project.com/download/stable/#download-lin - Install additional required packages: `sudo apt install make g++ git libx11-dev mesa-common-dev` - Go to a directory of your choice and clone the repository (it'll automatically create an `UltimateZoneBuilder` directory in the current directory): `git clone https://git.do.srb2.org/STJr/UltimateZoneBuilder.git` - Compile UDB: `cd UltimateZoneBuilder && make` - Run UDB: `cd Build && ./builder` **Links:** - [SRB2MB thread](https://mb.srb2.org/addons/ultimate-zone-builder.6126/) Ultimate Doom Builder: - [UDB repository](https://github.com/UltimateDoomBuilder/UltimateDoomBuilder) - [Original forum.zdoom.org thread](https://forum.zdoom.org/viewtopic.php?f=232&t=66745) More detailed info can be found in the **editor documentation** (Refmanual.chm)
