 You need the following packages: curl g++ gcc gmp make ncurses realpath xz-utils. Consult your distro documentation on the exact names of those packages.
 
 ### Darwin
 
+#### Generic
+
 On OS X, in the course of running ghcup you will be given a dialog box to install the command line tools. Accept and the requirements will be installed for you. You will then need to run the command again.
 On Darwin M1 you might also need a working llvm installed (e.g. via brew) and have the toolchain exposed in PATH.
 
 ### FreeBSD
 
+#### Generic
+
 The following distro packages are required: `curl gcc gmp gmake ncurses perl5 libffi libiconv`
 
-Notice that only FreeBSD 13.x is supported. If the installation fails, complaining about `libncursesw.8.so`, you will need to install FreeBSD 12 compat package first, for example, `pkg install misc/compat12x`.
 
 ### Windows
 
+#### Generic
+
 On Windows, msys2 should already have been set up during the installation, so most users should just proceed. If you are installing manually, make sure to have a working mingw64 toolchain and shell.
