More installation information and options: https://docs.brew.sh/Installation.

If running Linux or WSL, there are some pre-requisite packages to install.

You can set HOMEBREW_BREW_GIT_REMOTE and/or HOMEBREW_CORE_GIT_REMOTE in your shell environment to use geolocalized Git mirrors to speed up Homebrew's installation with this script and, after installation, brew update.

export HOMEBREW_BREW_GIT_REMOTE="..."  # put your Git mirror of Homebrew/brew here
export HOMEBREW_CORE_GIT_REMOTE="..."  # put your Git mirror of Homebrew/homebrew-core here
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

The default Git remote will be used if the corresponding environment variable is unset.

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/uninstall.sh)"

Download the uninstall script and run /bin/bash uninstall.sh --help to view more uninstall options.
