9Urbit can be installed on most Unix systems. There is no Windows
10port. Windows is a wonderful OS, we just haven't gotten to it yet.
15Urbit wants to map 2GB of memory when it boots up. We won't
16necessarily use all this memory, we just want to see it. On a
17normal modern PC or Mac, this is not an issue. On some small
18cloud virtual machines (Amazon or Digital Ocean), the default
19memory configuration is smaller than this, and you need to
20manually configure a swapfile.

37## Install as a package
41 brew install --HEAD homebrew/head-only/urbit
45Third-party packages are available, at:
47 https://github.com/yebyen/urbit-deb
49Urbit is only supported on Jessie onward (but outbound HTTPS
50requests only work on Stretch; I wish we knew why; help us!)
52## Hand-build from source
54First, install all external dependencies. Then, make.

93Although `automake`/`autoconf`/`libtool` are generally installed by
94default, some have reported needing to uninstall and reinstall those
95three packages, at least with Homebrew. Your mileage may vary.
