-
-#### macOS users (Homebrew)
-
-If you have not already done so, install [Homebrew](https://brew.sh).

-Then to install SDL and SDL2, execute the following command:
-
-```sh
-brew install sdl2 sdl12-compat
-eval "$(/opt/homebrew/bin/brew shellenv)"

-
-#### macOS users (MacPorts)

-Install [MacPorts](https://www.macports.org/install.php).

-To install SDL and SDL2, execute the following command as root:
-
-```sh
-dnf install SDL2 SDL2-devel sdl12-compat sdl12-compat-devel

-
-It was once possibly necessary to use `make` like:
-
-```sh
-make ... SDL2_INCLUDE_ROOT=/usr
-```
-
-or set the following environment variable:
-
-```sh
-export SDL2_INCLUDE_ROOT=/usr
-```
-
-but this is most likely unneeded as we use `sdl-config` and `sdl2-config` in the
-Makefiles.
