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