11Installing Urbit is easy. It just takes a few minutes to get an
12instance up and running on the network.
14Urbit is designed to run on any Unix box with an internet connection.
15macOS, Ubuntu/Debian, FreeBSD, and Fedora all work well.
17If you run into trouble installing Urbit, please let us know via
18email, [questions@urbit.org](mailto:questions@urbit.org), or on the
19forum: [fora.urbit.org](https://fora.urbit.org). You can also chat
20with us at [urbit.org/stream](https://urbit.org/stream).
22> Urbit is alpha software. It’s not yet completely stable, its crypto
23> hasn’t been audited, and there are plenty of rough edges. Urbit is
24> lots of fun to play with, but not quite ready for your important or
36C compiler (gcc or clang)
56First, you'll install the required dependencies to build Urbit from source. Then, you'll clone the Urbit source code, hosted on Github. Next, you'll bootstrap the Git submodules needed for the build. Lastly, you'll run a [Meson](https://github.com/mesonbuild/meson) build on the Urbit source to create your Urbit binary for your host operating system. Then, finally, you'll be able to boot your urbit.
58For your host OS platform and relevant package installer, run the respective Bash shell commands listed below in a fresh terminal window to get Urbit installed:

135N.B. if the step `./scripts/build` fails when attempting to
136build libh2o, it could be caused by a bug in version 0.46 of meson (the bug
137is not present in 0.45 and is fixed in 0.47).
139If the command `meson -v` returns a version starting with 0.46, try these steps:
143pip install meson=0.47.0
148If that is successful, resume the above instructions after the `build` step.

218### Test for successful installation
220After running your installed `urbit` command, check to see if the following output was printed:
224Urbit: a personal server operating function
228Usage: urbit [options...] ship_name
229where ship_name is a @p phonetic representation of an urbit address
230without the leading '~', and options is some subset of the following:
232-A dir Use dir for initial galaxy sync
234-B pill Bootstrap from this pill
235-c pier Create a new urbit in pier/
237-D Recompute from events
238-F Fake keys; also disables networking
241-H domain Set ames bootstrap domain (default urbit.org)
242-I galaxy Start as ~galaxy
243-k stage Start at Hoon kernel version stage
244-l port Initial peer port
246-n host Set unix hostname
247-N Enable networking in fake mode (-F)
248-p ames_port Set the HTTP port to bind to
251-r host Initial peer address
252-R Report urbit build info
253-s Pill URL from arvo git hash
254-t ticket Use ~ticket automatically
255-u url URL from which to download pill
257-w name Immediately upgrade to ~name
262 To create a development ship, use a fakezod:
263 urbit -FI zod -A /path/to/arvo/folder -B /path/to/pill -c zod
265 For more information about developing on urbit, see:
266 https://github.com/urbit/urbit/blob/master/CONTRIBUTING.md
269 urbit -c <mycomet> to create a comet (anonymous urbit)
270 urbit -w <myplanet> -t <myticket> if you have a ticket
271 urbit <myplanet or mycomet> to restart an existing urbit
274If so, then you're ready to boot your urbit. If not, check that you entered each Bash command correctly for your host OS platform. If you're still experiencing issues, feel free to drop into [Urbit chat](https://urbit.org/stream) for troubleshooting help.
278You've now installed the Urbit binary. If you're running Urbit on a normal modern PC or Mac, or
279on a large cloud instance, move onto the next [setup](../setup/) section.
281If you're running Urbit in the cloud on a small instance, read
282the below section, as you may need to additionally configure swap space, then continue.
286Urbit wants to map 2GB of memory when it boots up. We won’t necessarily
287use all this memory, we just want to see it. On a normal modern PC or Mac,
288or on a large cloud virtual machine, this is not an issue. On some small
289cloud virtual machines (Amazon or Digital Ocean), the default memory
290configuration is smaller than this, and you need to manually configure a
293Digital Ocean has a post on adding swap
294[here](https://www.digitalocean.com/community/tutorials/how-to-add-swap-space-on-ubuntu-16-04).
295For Amazon there’s a StackOverflow thread
296[here](http://stackoverflow.com/questions/17173972/how-do-you-add-swap-to-an-ec2-instance).
