We suggest the following installation.

1. First install [GHCup](https://www.haskell.org/ghcup/). When asked, answer Yes to adding the ghcup installation directory to PATH.
- On Windows: copy the install script from the GHCup webpage into PowerShell. The installation might take a long time (10+ minutes), apparently because of the Windows Defender antivirus checking the installation very slowly.
2. Then use it to install Stack and GHC. On Windows, starting from here, input the commands in Git Bash.
```
ghcup install stack latest
ghcup install ghc 9.4.8
```
If you have not yet done it, add to your system `PATH` the location where GHCup installs tools.

3. Finally, use Stack to install the remaining tools.

- On Windows: copy the install script from the GHCup webpage into PowerShell. The installation might take a long time (10+ minutes), apparently because of the Windows Defender antivirus checking the installation very slowly. After this is finished, work in Git Bash for all of the following steps.

3. Use Stack to install the remaining tools.

stack install alex happy BNFC
