Here's what you're going to need:


* Ruby 1.8.0 or higher.

** Linux/FreeBSD: "Get the latest, please.":http://ruby-lang.org/en/20020102.html

** Windows: "Installer for Windows.":http://rubyinstaller.sourceforge.net/

** Mac: "OSX disk image.":http://homepage.mac.com/discord/Ruby/

* Once Ruby is installed, open a command prompt and type:


<pre>
  ruby -ropen-uri -e 'eval(open("http://go.hobix.com/").read)'
</pre>

Ok, so the idea here is that one whole weblahhg is contained
in a single directory.  What is stored in the directory?


<pre>
  hobix.yaml <- configuration

  entries/   <- edit and organize
                your news items,
                articles and so on.

  skel/      <- contains your
                templates

  htdocs/    <- html is created here,
                store all your images here,
                this is your viewable
                websyht

  lib/       <- extra hobix libraries
                (plugins) go here
</pre>


One weblahhg can be shared with many authors.  In the @hobix.yaml@
file, you can store information about each author, as well as 
information about others who contribute to your websyht.


You also have a file of your own, a configuration file called
@.hobixrc@, which contains a list of the weblahhgs you belong
to.


h2. Pull One From the Sky


If you would like to create your own weblahhg from scratch:


<pre>
  hobix create blahhg
</pre>


You will be prompted for a full path where the new weblahhg can
be created.  Don't worry if the directory doesn't yet exist,
Hobix will take care of clearing a path for it.


Once you give it the path, Hobix will create all the necessary
directories, as well as the @hobix.yaml@.  You should also have
a set of sample templates to get you started.


In fact, if you want to generate the default site:


<pre>
  hobix regen blahhg
</pre>


h2. Joining Hands With Others


To join an existing weblahhg:


<pre>
  hobix add other-blahhg /path/to/other-blahhg/hobix.yaml
</pre>


You don't need to be on a weblahhg's author list to join the weblahhg.
You just need permissions to edit the file.


h2. Leaving in a Cloud of Keystrokes


To remove a weblahhg from your configuration:


<pre>
  hobix del other-blahhg
</pre>


Please don't be afraid to edit your configuration file yourself,
should the commandline not suit your style.


See, here's my @.hobixrc@:


<pre>
  --- 
  weblogs: 
    hobix: /usr/local/www/hobix.com/www/hobix.yaml
    why: /usr/local/www/whytheluckystiff.net/www/hobix.yaml
  username: why
  use editor: true
</pre>


That's a YAML file.  Very simple to edit.  You can manually edit
your information, safely add or edit your weblogs, and save back
to your @.hobixrc@.


Enough then.  Time to trick out your new Hoblahhg.
You will be guided through an automatic installation (or upgrade) of
Hobix.
STR2
NOW BUNKING together: the ruby and yaml scripts up at http://go.hobix.com/. Hey ,, the life and unity we feel is tree-mending-US!!

Try:

<pre>
  ruby -ropen-uri -e'eval open("http://go.hobix.com/").read'
</pre>

No longer are curtains dropping ON the actors' arms !!  No longer are swift currents ON the actors' legs !!  The actors have a bottomless cereal container, witness.

  One weblahhg can be shared with many authors.  In the @hobix.yaml@
  file, you can store information about each author, as well as 
  information about others who contribute to your websyht.


  You also have a file of your own, a configuration file called
  @.hobixrc@, which contains a list of the weblahhgs you belong
  to.


  h2. Pull One From the Sky


  If you would like to create your own weblahhg from scratch:


  <pre>
    hobix create blahhg
  </pre>


  You will be prompted for a full path where the new weblahhg can
  be created.  Don't worry if the directory doesn't yet exist,
  Hobix will take care of clearing a path for it.


  Once you give it the path, Hobix will create all the necessary
  directories, as well as the @hobix.yaml@.  You should also have
  a set of sample templates to get you started.


  In fact, if you want to generate the default site:


  <pre>
    hobix regen blahhg
  </pre>


  h2. Joining Hands With Others


  To join an existing weblahhg:


  <pre>
    hobix add other-blahhg /path/to/other-blahhg/hobix.yaml
  </pre>


  You don't need to be on a weblahhg's author list to join the weblahhg.
  You just need permissions to edit the file.


  h2. Leaving in a Cloud of Keystrokes


  To remove a weblahhg from your configuration:


  <pre>
    hobix del other-blahhg
  </pre>


  Please don't be afraid to edit your configuration file yourself,
  should the commandline not suit your style.


  See, here's my @.hobixrc@:


  <pre>
    --- 
    weblogs: 
      hobix: /usr/local/www/hobix.com/www/hobix.yaml
      why: /usr/local/www/whytheluckystiff.net/www/hobix.yaml
    username: why
    use editor: true
  </pre>


  That's a YAML file.  Very simple to edit.  You can manually edit
  your information, safely add or edit your weblogs, and save back
  to your @.hobixrc@.


  Enough then.  Time to trick out your new Hoblahhg.
  You will be guided through an automatic installation (or upgrade) of
  Hobix.
