<h3>Community</h3>
<p>
GraphX is developed as part of the Apache Spark project. It thus gets
tested and updated with each Spark release.
</p>
<p>
If you have questions about the library, ask on the
<a href="/community.html#mailing-lists">Spark mailing lists</a>.
</p>
<p>
GraphX is in the alpha stage and welcomes contributions. If you'd like to submit a change to GraphX,
read <a href="https://cwiki.apache.org/confluence/display/SPARK/Contributing+to+Spark">how to
contribute to Spark</a> and send us a patch!
</p>
</div>
<div class="col-md-6 col-padded">
<h3>Getting Started</h3>
<p>
To get started with GraphX:
</p>
<ul class="list-narrow">
<li><a href="/downloads.html">Download Spark</a>. GraphX is included as a module.</li>
<li>Read the <a href="/docs/latest/graphx-programming-guide.html">GraphX guide</a>, which includes
usage examples.</li>
<li>Learn how to <a href="/docs/latest/#launching-on-a-cluster">deploy</a> Spark on a cluster
if you'd like to run in distributed mode. You can also run locally on a multicore machine
without any setup.
</li>
