+## Supported systems
+We try to **support** all major *NIX systems: all Linux distros but also NetBSD, OpenBSD and macOS,
+provided the OS version was released within the past ~5 years.
+
+We use a private BuildBot instance to test each commit. The **tested** systems are (others are
+likely to work too):
+* Linux: Debian (10, 11, 12, 13), Ubuntu (18.04, 20.04, 22.04, 24.04, 26.04)
+* FreeBSD: 15
+* Windows: Visual Studio 2019
+
+UnrealIRCd is architecture-agnostic. Most of the BuildBot workers run on x64 but we
+also have some on x86 and arm64 to ensure these work as well.
