<p>This document gives step-by-step instructions for deploying <a href="http://singa.apache.org">SINGA website</a>. SINGA website is built by <a href="http://www.sphinx-doc.org">Sphinx</a> from a source tree stored in the <a href="https://github.com/apache/singa/tree/master/doc">git repo</a>.</p>
<p>To install Sphinx:</p>
<pre><code class="hljs">pip install -U Sphinx==1.5.6
</code></pre>
<p>To install the markdown support for Sphinx:</p>
<pre><code class="hljs">pip install recommonmark==0.5.0
</code></pre>
<p>To install the rtd theme:</p>
<pre><code class="hljs">pip install sphinx_rtd_theme==0.4.3
</code></pre>
<p>You can build the website by executing the following command from the doc folder:</p>
<pre><code class="hljs">./build.sh html
</code></pre>
<p>Committers can update the <a href="http://singa.apache.org/en/index.html">SINGA website</a> by copying the updated files to the <a href="https://github.com/apache/singa-site">website repo</a> (suppose the site repo is ~/singa-sit)</p>
<pre><code class="hljs">cd _build
rsync --checksum -rvh html/ ~/singa-site/
cd ~/singa-site
git commit -m &quot;update xxxx&quot;
git push
</code></pre>
<p>We fix the versions of the libs in order to generate the same (checksum) html file if the source file is not changed. Otherwise, everytime we build the documentation, the html file of the same source file could be different. As a result, many html files in the site repo need updating.</p>
