-# Getting started
+# Installation
 
 GHCup makes it easy to install specific versions of GHC on GNU/Linux,
 macOS (aka Darwin), FreeBSD and Windows and can also bootstrap a fresh [Haskell developer environment](./install/#supported-tools) from scratch.
 It follows the UNIX philosophy of [do one thing and do it well](https://en.wikipedia.org/wiki/Unix_philosophy#Do_One_Thing_and_Do_It_Well). Similar in scope to [rustup](https://github.com/rust-lang-nursery/rustup.rs), [pyenv](https://github.com/pyenv/pyenv) and [jenv](http://www.jenv.be).
 
-## Installation
+## How to install
 
 The following commands will download the `ghcup` binary into `~/.ghcup/bin` (or `C:\ghcup\bin` on windows) and then
 run it to interactively install the [Haskell Toolchain](#supported-tools). These commands should be run as **non-root/non-admin

+
+The following distro packages are required: `binutils-gold curl gcc g++ gmp-dev libc-dev libffi-dev make musl-dev ncurses-dev perl tar xz`
+
+### Linux (generic)
+
+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
+
+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
+
+The following distro packages are required: `curl gcc gmp gmake ncurses perl5 libffi libiconv`
+
+### Windows
+
+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.
