 3. handling cabal projects
 4. being a stack alternative
 
+## Distribution policies
+
+Like most Linux distros and other distribution channels, GHCup also
+follows certain policies. These are as follows:
+
+1. The end-user experience is our primary concern
+    - ghcup in CI systems as a use case is a first class citizen
+2. We strive to collaborate with all maintainers of all the tools we support and maintain a good relationship
+3. We may fix build system or other distribution bugs in upstream bindists
+    - these are always communicated upstream
+4. We may even patch source code of supported tools in very rare cases if that is required to ensure that the end-user experience does not break
+    - we'll first try to upstream any such required patch and request a new release to avoid downstream patching
+    - patches will be communicated to the maintainers either way and we'll strive to get their review
+    - they will also be communicated to the end-user
+    - they will be uploaded along with the bindist

 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).

 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.

+
 The following distro packages are required: `curl gcc gmp gmake ncurses perl5 libffi libiconv`

 ### 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.

+1. Install ghcup binary
+    - choose a base directory for installation, e.g. `C:\` that has sufficient space
+    - then create the directory, e.g. `C:\ghcup\bin`
+    - download the binary: https://downloads.haskell.org/~ghcup/x86_64-mingw64-ghcup.exe
+    - place it as `ghcup.exe` into e.g. `C:\ghcup\bin`
+2. Install MSYS2
+    - download https://repo.msys2.org/distrib/msys2-x86_64-latest.exe and execute it
+    - remember the installation destination you choose (default is `C:\msys64`)
+    - finish the installation
+* Add environment variables and update `Path`
+    - open search bar and type in "Edit the system environment variables", then open it
+    - click on "Environment Variables..." at the near bottom
+    - in the upper half, select `Path` variable and double click on it
+    - in the new window, click "New", type in `C:\ghcup\bin` (depending on step 1.) and press enter
+    - click "OK" at the bottom
+    - in the upper half, click on "New..."
+    - enter `GHCUP_MSYS2` under "Variable name" and the installation destination from step 2. under "Variable value"
+    - click "OK" at the bottom
+    - in the upper half, click on "New..."
+    - enter `GHCUP_INSTALL_BASE_PREFIX` under "Variable name" and based on the installation destination from step 1. enter the device directory (default `C:\`)
+    - click "OK" at the bottom
+    - in the upper half, click on "New..."
+    - enter `CABAL_DIR` under "Variable name" and based on the installation destination from step 1. enter the device directory + `cabal` subdir (default `C:\cabal`)
+    - click "OK" at the bottom
+    - click "OK" at the bottom
+    - click "OK" at the bottom
+3. Install tools
+    - open powershell
+    - run `ghcup install ghc --set recommended`
+    - run `ghcup install cabal latest`
+    - run `ghcup install stack latest`
+    - run `ghcup install hls latest`
+    - run `cabal update`
+4. Update msys2
+    - run `ghcup run -m -- pacman --noconfirm -Syuu`
+    - run `ghcup run -m -- pacman --noconfirm -Syuu`
+    - run `ghcup run -m -- pacman --noconfirm -S --needed curl autoconf mingw-w64-x86_64-pkgconf`
+    - run `ghcup run -m -- pacman --noconfirm -S ca-certificates`
+5. Update cabal config
+    - go to e.g. `C:\cabal` (based on device you picked in 1.)
+    - open file `config`
+    - uncomment `extra-include-dirs` (the `-- `) and add the value (depending on installation destination you chose in 2.), e.g. `C:\msys64\mingw64\include`... so the final line should be `extra-include-dirs: C:\msys64\mingw64\include`
+    - uncomment `extra-lib-dirs` and do the same, adding `C:\msys64\mingw64\lib`
+    - uncomment `extra-prog-path` and set it to `C:\ghcup\bin, C:\cabal\bin, C:\msys64\mingw64\bin, C:\msys64\usr\bin`, depending on your install destinations from 1. and 2.
+6. Set up msys2 shell
+    - run `ghcup run -m -- sed -i -e 's/db_home:.*$/db_home: windows/' /etc/nsswitch.conf` to make the HOME in your msys2 shell match the one from windows
+    - make a desktop shortcut from `C:\msys64\msys2_shell.cmd`, which will allow you to start a proper msys2 shell
+    - run `ghcup run -m -- sed -i -e 's/#MSYS2_PATH_TYPE=.*/MSYS2_PATH_TYPE=inherit/' /c/msys64/msys2.ini`
+    - run `ghcup run -m -- sed -i -e 's/rem set MSYS2_PATH_TYPE=inherit/set MSYS2_PATH_TYPE=inherit/' /c/msys64/msys2_shell.cmd`

+## Esoteric distros
+
+### Void Linux
+
+Since void linux can be installed with glibc and musl, it's hard to support correctly with ghcup.
+One way to make ghcup work on **Void Linux musl** is to follow the [Overriding distro detection](../guide/#overriding-distro-detection)
+section and tell it to consider Alpine bindists only. E.g.:
+
+```sh
+curl --proto '=https' --tlsv1.2 -sSf https://get-ghcup.haskell.org | BOOTSTRAP_HASKELL_MINIMAL=1 sh
+source ~/.ghcup/env
+ghcup config set platform-override '{ "arch": "A_64", "platform": { "contents": "Alpine", "tag": "Linux" }, "version": "3.17" }'
+ghcup install cabal --set latest
+ghcup install ghc --set latest
+ghcup install stack --set latest
+ghcup install hls --set latest
+```
