 Homebrew does not currently support 32-bit x86 platforms. It would be possible for Homebrew to work on 32-bit x86 platforms with some effort. An interested and dedicated person could maintain a fork of Homebrew to develop support for 32-bit x86.
 
-## Alternative Installation
-
-Extract or `git clone` Homebrew wherever you want. Use `/home/linuxbrew/.linuxbrew` if possible (to enable the use of binary packages).
-
-```sh
-git clone https://github.com/Homebrew/brew ~/.linuxbrew/Homebrew
-mkdir ~/.linuxbrew/bin
-ln -s ~/.linuxbrew/Homebrew/bin/brew ~/.linuxbrew/bin
-eval "$(~/.linuxbrew/bin/brew shellenv)"

 ### Multiple installations
 
 Create a Homebrew installation wherever you extract the tarball. Whichever `brew` command is called is where the packages will be installed. You can use this as you see fit, e.g. a system set of libs in the default prefix and tweaked formulae for development in `~/homebrew`.
