Arvados

h1. Documentation project

The documentation project is a part of the overall Arvados project. The output from this project forms the official documentation at "http://doc.arvados.org":http://doc.arvados.org. It is also included in the Arvados source tree.

h2. Guides

There are six guides that are being developed to support the use of Arvados: 

* "Getting Started":http://doc.arvados.org/start/ - Quickstart and overview of Arvados (what it is, who it's for, and key features).

* "User Guide":http://doc.arvados.org/user/ - Introductory and tutorial materials for building analysis or web applications using Arvados.

* "SDK Reference":http://doc.arvados.org/sdk/ - Details about the accessing Arvados from various programming languages.

* "API Reference":http://doc.arvados.org/api/ - REST API methods and resources, the MapReduce job execution environment, permission model, etc.

* "Admin Guide":http://doc.arvados.org/admin/ - Instructions to system administrators for maintaining an Arvados installation.

* "Install Guide":http://doc.arvados.org/install/ - How to install and configure Arvados on the cloud management platform of your choice.

A web version of the documentation is available at http://doc.arvados.org.

h2. Documentation Project

The Arvados documentation is written in Markdown, Textile, and HTML. The source code is in the @doc@ directory in the Arvados source tree. We use Jekyll to render HTML pages.

h2. Contributing

Bugs in the documentation can be submitted as "issues":/projects/arvados/issues. 

If you'd like to fix documentation bugs yourself, or to otherwise contribute to the documentation, clone the Arvados source repository, edit, and send pull requests just as you would when contributing program source code.

We do not yet maintain a separate documentation mailing list, so we encourage documentation contributors to join the main developer mailing list.

Contributor quick-start:

# Fork the arvados repository on github

# Clone the repository and set up the preprocessor

#* <pre><code>git clone git://github.com/<b>your_github_username</b>/arvados.git

cd arvados/doc

bundle install

</code></pre>

# Generate html (it will appear in @.site/@) and start an http server with your local copy

#* <pre><code>rake

rake run

</code></pre>

# Preview in your browser at http://localhost:8000

To generate Python SDK docs, install @epydoc@ and @arvados-python-client@ before running @rake@ in @arvados/doc@:

<pre><code>sudo apt-get install python-pip python-virtualenv

virtualenv /tmp/z

source /tmp/z/bin/activate

pip install epydoc arvados-python-client

rake

</code></pre>

When you want to start making changes to the site, do so on a branch. If you'd like to follow our development process, create or pick an existing issue. For documentation purposes, https://arvados.org/issues/4926 is a safe bet. Note the issue number: *4926*.

Then,

# Fork the arvados repository on github

# Make a feature branch

# <pre><code>git checkout -b 4926-some-description</code></pre>

# Make your changes to the documentation

# Preview your changes with @git status@, @git diff@, etc.

# Add and commit the files you want to include in the update. For example:

# <pre><code>git add _config.yml _includes/_navbar_top.liquid _layouts/default.html.liquid index.html.liquid

git commit -m "4926: Added foobar to barfoo"

</code></pre>

# Push the branch to your github account

<pre><code>git push git@github.com:<b>your_github_username</b>/arvados.git 4926-getting-started:4926-getting-started

</code></pre>

# Go to https://github.com and create a pull request

We like to see commit messages that start with an issue number (if applicable) and describe what the new code _does_, like this:

* "1234: Explain it's important to install foo before baz."

* "1234: Update foo example to use new bar feature."

Less-good messages:

* "Improve docs."

* "Incorporate review feedback."

h3. Code Review

Next, get it reviewed and merged!

We should get notified when new PRs arrive, but if you'd like to move things along faster we'll be happy to hear from you one or more of the following ways:

* visit our IRC channel

* send email to support@curoverse.com

* Visit our "redmine issue tracker":http://arvados.org and add a review subtask under the appropriate issue, if applicable -- just enter the subject "review 4926-some-description" and we'll know what it means.
