+# Homebrew (un)installer
+
+## Install Homebrew (on macOS or Linux)
+
+```bash
+/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
+```
+
+More installation information and options: <https://docs.brew.sh/Installation>.
+
+If you're on macOS, try out our new `.pkg` installer. Download it from [Homebrew's latest GitHub release](https://github.com/Homebrew/brew/releases/latest).
+
+If you are running Linux or WSL, [there are some pre-requisite packages to install](https://docs.brew.sh/Homebrew-on-Linux#requirements).
+
+You can set `HOMEBREW_NO_INSTALL_FROM_API` to tap Homebrew/homebrew-core; by default, it will not be tapped as it is no longer necessary.
+
+You can set `HOMEBREW_BREW_GIT_REMOTE` and/or `HOMEBREW_CORE_GIT_REMOTE` in your shell environment to use geolocalized Git mirrors to speed up Homebrew's installation with this script and, after installation, `brew update`.
+
+```bash
+export HOMEBREW_BREW_GIT_REMOTE="..."  # put your Git mirror of Homebrew/brew here
+export HOMEBREW_CORE_GIT_REMOTE="..."  # put your Git mirror of Homebrew/homebrew-core here
+/bin/bash -c "$(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.
+
+If you want to run the Homebrew installer non-interactively without prompting for passwords (e.g. in automation scripts), you can use:
+
+```bash
+NONINTERACTIVE=1 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
+```
+
+## Uninstall Homebrew
+
+```bash
+/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/uninstall.sh)"
+```
+
+If you want to run the Homebrew uninstaller non-interactively, you can use:
+
+```bash
+NONINTERACTIVE=1 /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.
