 ## Installation
 
+### Supported platforms
+
+This list may not be exhaustive and specifies support for bindists only.
+
+| Platform | Architecture | ghcup | GHC | cabal | HLS | stack | 
+| ------ | ------ | ------ | ------ | ------ | ------ | ------ |
+| Windows 7 | amd64 | ❔ | ✅ | ✅ | ✅ | ✅ |

+
+#### Windows 7
+
+May or may not work, several issues:
+
+* https://gitlab.haskell.org/haskell/ghcup-hs/-/issues/140
+* https://gitlab.haskell.org/haskell/ghcup-hs/-/issues/197
+
+#### WSL1
+
+Unsupported. GHC may or may not work. Upgrade to WSL2.
+
+#### MacOS <13
+
+Not supported. Would require separate binaries, since >=13 binaries are incompatible.
+Please upgrade.
+
+#### MacOS aarch64
+
+HLS bindists are still experimental. Stack is theoretically supported, but has no binaries yet.
+
+#### FreeBSD
+
+Lacks some upstream bindists and may need compat libs, since most bindists are built on FreeBSD-12.
+
+#### Linux ARMv7/AARCH64
+
+Lower availability of bindists. HLS only has experimental ones. Stack now supported currently.
+
 ### Simple bootstrap
