How do I run Diablo on my MacOS?

[MacBH928]

I was told I can run original Diablo if I use this:

GitHub - diasurgical/devilution: Diablo devolved - magic behind the 1996 computer game

Diablo devolved - magic behind the 1996 computer game - diasurgical/devilution

github.com

can any one tell me how? do I have to compile the source code myself?
I know I have to get the original licensed game from GOG.

I have the installation MD file for Mac that says this:

# Installation

## Dependencies

[Homebrew](https://brew.sh/)

```bash
brew install wine
brew install mingw-w64
```

## Building

```bash
git clone [URL]https://github.com/galaxyhaxz/devilution[/URL]
cd devilution
cp /path/to/diablo_game_dir/diabloui.dll .
cp /path/to/diablo_game_dir/Storm.dll .
make
```

## Install

```bash
cp devilution.exe /path/to/diablo_game_dir/
```

## Run

```bash
wine devilution.exe
```

I only know that the first two commands will install Wine and something called mingw-w64. Thats all I know. Probably the last line launches the game. I don't know what is " ```bash" means. Any GUI instructions!?
