Install a package Code of conduct
----------------- ---------------
#### OS X - Homebrew Everyone involved in the Urbit project needs to understand and
respect our code of conduct, which is: "don't be rude."
Documentation
=============
In-progress documentation can be found at
[urbit.org/docs](http://urbit.org/docs).
These docs ship with your urbit. If you're running one locally you
can access them at
http://localhost:8080/home/docs
Assuming you're running on port 8080. The port is printed on startup.
Install
=======
Urbit can be installed on most Unix systems. There is no Windows
port. Windows is a wonderful OS, we just haven't gotten to it yet.
Use a VM.

As a comet, you're not necessarily a bad person. But you could
be anyone, so you have zero reputation. You have no official
access to any Urbit services. Any connectivity you may enjoy
could be shut off at any time. And probably will be.

some firewalls may not like it. Urbit without connectivity isn't
useless, but it can't boot without the network.
But however horribly hacked, the `urbit` process can only read ~fintud-macrep:talk()
and write inside the `fintud-macrep` or `mycomet` directory,
which we call your *pier*. A pier is portable; any Urbit install
on any OS can execute the same pier.
In the pier directory is a set of user-level mount points. Mount or
points are synced Dropbox style, with Unix file changes
autocommitted to the Urbit revision control system (`%clay`) and
vice versa. You edit Urbit code with vim and emacs, or whatever.
Also within the pier is a system directory, `.urb`, which ~fintud-macrep:dojo>
contains an event log (`egz.hope`), a checkpoint (`.chk`), and
I/O directories for uploads and downloads (`put` and `get`).
You can compact the pier by deleting the checkpoint, although
that means Urbit needs to re-execute its entire event history.
This will take some time. Go have a beer.

and then press ^D to quit. Your urbit is born.
Execute
-------
To restart your urbit, run with the pier name:
urbit fintud-macrep
urbit mycomet
Your Urbit is a database, at least in theory. You can kill the
process however you like, and it won't lose state. In theory.
In practice, this works better on OS X than Linux. Also, don't
let your filesystem run out of disk!
Out of the box, your urbit is running two default appliances,
`:dojo` (a shell or REPL) and `:talk`. Switch between them with
`^X`. Note that all apps share an output log, but `^X` switches
the prompt.
`^D` from any default appliance exits the urbit process.

Basics
------
`^v` will switch between the task manager and the focussed process. `^x`
will switch between processes.
To start a process that is not yet started, run `*proc` from the task
manager.
To connect your console to a process that has already been started, run
`+proc` from the task manager. Note that the process must be one that
supports console access, such as dojo and talk.
`^d` will exit the pier from the task manager. No matter how you shut
your urbit down you'll be returned to exactly the same state as when you
turned it off.
Talk
----
If you're on the network, you can use its most basic application,
`talk`.
If `talk` is not running, start it with `*talk` from the task manager.
Use `^x` to switch to the `talk` prompt and then run
;join ~doznec/urbit-meta
to join the `urbit-meta` channel. People in there are helpful.
There are three main `talk` commands:
;join ~urbit-name/channel
`;join` subscribes your main feed to a remote channel.
;<number>
`;<number>` activates a previous message number, like a URL that got
clipped.
;<target>
`;<target>` sets the target for your messages, such as `;~urbit-name`
for a private message.
Filesystem Sync
---------------
The Urbit filesystem, `%clay` doesn't automatically sync to unix. If
you'd like to browse the contents of your Urbit from unix you'll need to
use `|mount`.
`|mount` creates a mirror in unix of files from `%clay` that is always
watching for changes. To sync your entire `home/` desk run:
|mount %
you should see a directory called `home/` get created inside your pier.
When you change files in this directory the changes will get synced into
your urbit.
Since each mount point is always watching for changes you may also want
to unmount from time to time.
The full syntax is as follows (from `dojo`):
|mount <path-in-clay> [<mount-name>]
The `<mount-name>` is optional and defaults to the last part of
the `<path-in-clay>`.
|unmount <mount-name>
or:
|unmount <path-in-clay>
Sysadmin
--------
For the most part, updates to the system are automatically synced to
your urbit across the network.
When we make updates to the interpreter you should be able to shut down
your urbit and:
git pull origin master
make
bin/urbit pier
where pier is the name of your pier.
While the network is still young from time to time we reboot the entire
universe. We call this a 'continuity breach' since we're breaking the
continuity of our crypto.
When this happens you'll need to back up your data and start a fresh
pier. Your original ticket will still work.
