-Solanum is designed with portability in mind, but does not target older systems nor those of solely academic
-interest.
-
-Do note that operating systems are only supported if they are supported by their vendor.
-
-## Tier 1
-
-These platforms are the best supported, and should always work. They are actively tested. If you encounter
-problems, please file a bug.
-
-* FreeBSD 10.x and above (i386 and amd64)
-* Linux 2.6.x and above with glibc or musl (i386, x86_64, and ARM)
-* macOS 10.7 and above
-* Windows Vista/Server 2008 and above (x86 or x64)
-
-## Tier 2
-
-These platforms are supported and occasionally tested, and most features should work, but this is not
-guaranteed. If you find any problems, file a bug, but as these are not regularly tested platforms, a timely
-resolution may not be possible.
-
-* DragonflyBSD 4.4 and above (i386)
-* Linux with uClibc (i386 or x86_64)
-* NetBSD 6.1.x and above (i386, amd64)
-* OpenBSD 5.6 and above (i386, amd64)
-* Solaris 10 and above (i386)
-
-## Tier 3
-
-Anything else that hasn't been tested. Solanum may or may not work on it; patches welcome if they don't.
+Solanum is developed on Linux with glibc, but is currently portable to most POSIX-compatible operating systems.
+However, this portability is likely to be removed unless someone is willing to maintain it. If you'd like to be that
+person, please let us know on IRC.
