What I was trying to do (and why):
Well, I tried to install Linuxbrew although the README.MD states that it wouldn't work on my system.
What happened:
The command sh -c "$(curl -fsSL https://raw.githubusercontent.com/Linuxbrew/install/master/install.sh)" successfully installed Linuxbrew.

Output:

==> Installation successful!

==> Homebrew has enabled anonymous aggregate user behaviour analytics.
Read the analytics documentation (and how to opt-out) here:
  https://docs.brew.sh/Analytics.html

==> Next steps:
- Install the Linuxbrew dependencies if you have sudo access:
  Debian, Ubuntu, etc.
    sudo apt-get install build-essential
  Fedora, Red Hat, CentOS, etc.
    sudo yum groupinstall 'Development Tools'
  See http://linuxbrew.sh/#dependencies for more information.
- Add Linuxbrew to your ~/.zprofile by running
    echo 'export PATH="/home/linuxbrew/.linuxbrew/bin:$PATH"' >>~/.zprofile
    echo 'export MANPATH="/home/linuxbrew/.linuxbrew/share/man:$MANPATH"' >>~/.zprofile
    echo 'export INFOPATH="/home/linuxbrew/.linuxbrew/share/info:$INFOPATH"' >>~/.zprofile
- Add Linuxbrew to your PATH
    PATH="/home/linuxbrew/.linuxbrew/bin:$PATH"
- We recommend that you install GCC by running:
    brew install gcc
- Run `brew help` to get started
- Further documentation: 
    https://docs.brew.sh
Warning: /home/linuxbrew/.linuxbrew/bin is not in your PATH.

What I expected to happen:
That the installation would fail.
Step-by-step reproduction instructions (not by running brew commands):
- Buy a 32-bit machine (don't do that, seriously)
- Run sh -c "$(curl -fsSL https://raw.githubusercontent.com/Linuxbrew/install/master/install.sh)".
  
  Features

My proposal is to edit the README.MD. It shouldn't say that "Linuxbrew does not currently support 32-bit x86 platforms", because it actually does. Maybe not every distro, maybe not fully. But as you can see, it supports my 32-bit x86 platform so it supports at least one.

How the feature would be relevant to at least 90% of Linuxbrew users? It probably isn't even relevant to 10% of Linuxbrew users, but maybe relevant to 100% not-yet-Linuxbrew-users which are working on a 32-bit x86 platform.

What alternatives to the feature have I considered: None.

We currently use circle-ci to build our binary files. Sometimes I build bottles on my private computer when we need a lot of memory (like when we build llvm).

Thanks for the proposal but we would support 32 bit binary builds only if:

the computer is stored in a server room and has a 99% uptime guarantee.
there is a new maintainer who works on this at least 5 hours per week

I am mostly running homebrew-core alone, with the support of 2-3 other people that work more on the infrastructure or sometimes help out on the formulae. I already struggle with the workload, so I am -1 on adding 32 bit support without more maintainers and funding :)

I'm glad to hear that Linuxbrew is working for you on your 32-bit Intel system, Nano. We don't build precompiled binary bottles for 32-bit Intel, and we don't test on 32-bit Intel systems, so it's not guaranteed to work flawlessly, but if it works for you, great. I'll update the README to that effect after the release of Linuxbrew 1.5.0 in a couple of weeks.

Alright, nice. Thanks! I could provide you precompiled bottles whenever you want. Just need information about how exactly that works...

EDIT: I mean, you don't build them because you don't have a 32-bit system, am I right? Well, I have one and I'm available! :D
