<h1>如何贡献/修改文档<a class="headerlink" href="#id1" title="永久链接至标题">¶</a></h1>
<p>PaddlePaddle的文档包括英文文档 <code class="docutils literal"><span class="pre">doc</span></code> 和中文文档 <code class="docutils literal"><span class="pre">doc_cn</span></code> 两个部分。文档都是通过 <a class="reference external" href="https://cmake.org/">cmake</a> 驱动 <a class="reference external" href="http://www.sphinx-doc.org/en/1.4.8/">sphinx</a> 编译生成，生成后的文档分别存储在编译目录的 <code class="docutils literal"><span class="pre">doc</span></code> 和 <code class="docutils literal"><span class="pre">doc_cn</span></code> 两个子目录下。</p>
<div class="section" id="paddlepaddle">
<h2>如何构建PaddlePaddle的文档<a class="headerlink" href="#paddlepaddle" title="永久链接至标题">¶</a></h2>
<p>PaddlePaddle的文档构建有直接构建和基于Docker构建两种方式，我们提供了一个构建脚本build_docs.sh来进行构建。
PaddlePaddle文档需要准备的环境相对较复杂，所以我们推荐使用基于Docker来构建PaddlePaddle的文档。</p>
<div class="section" id="dockerpaddlepaddle">
<h3>使用Docker构建PaddlePaddle的文档<a class="headerlink" href="#dockerpaddlepaddle" title="永久链接至标题">¶</a></h3>
<p>使用Docker构建PaddlePaddle的文档，需要在系统里先安装好Docker工具包。Docker安装请参考 <a class="reference external" href="https://docs.docker.com/">Docker的官网</a> 。安装好Docker之后可以使用源码目录下的脚本构建文档，即</p>
<div class="highlight-bash"><div class="highlight"><pre><span></span><span class="nb">cd</span> TO_YOUR_PADDLE_CLONE_PATH
<span class="nb">cd</span> paddle/scripts/tools/build_docs
bash build_docs.sh with_docker
</pre></div>
</div>
<p>编译完成后，会在当前目录生成两个子目录:</p>
<ul class="simple">
<li>doc 英文文档目录</li>
<li>doc_cn 中文文档目录</li>
</ul>
<p>打开浏览器访问对应目录下的index.html即可访问本地文档。</p>
</div>
<div class="section" id="id2">
<h3>直接构建PaddlePaddle的文档<a class="headerlink" href="#id2" title="永久链接至标题">¶</a></h3>
<p>因为PaddlePaddle的v2 api文档生成过程依赖于py_paddle Python包，用户需要首先确认py_paddle包已经安装。</p>
<div class="highlight-bash"><div class="highlight"><pre><span></span>python -c <span class="s2">&quot;import py_paddle&quot;</span>
</pre></div>
</div>
<p>如果提示错误，那么用户需要在本地编译安装PaddlePaddle，请参考 <a class="reference external" href="http://doc.paddlepaddle.org/develop/doc/getstarted/build_and_install/build_from_source_en.html">源码编译文档</a> 。
注意，用户在首次编译安装PaddlePaddle时，请将WITH_DOC选项关闭。在编译安装正确之后，请再次确认py_paddle包已经安装，即可进行下一步操作。</p>
<p>如果提示正确，可以执行以下命令编译生成文档，即</p>
<div class="highlight-bash"><div class="highlight"><pre><span></span><span class="nb">cd</span> TO_YOUR_PADDLE_CLONE_PATH
<span class="nb">cd</span> paddle/scripts/tools/build_docs
bash build_docs.sh <span class="nb">local</span>
</pre></div>
</div>
<p>编译完成之后，会在当前目录生成两个子目录:</p>
<ul class="simple">
<li>doc 英文文档目录</li>
<li>doc_cn 中文文档目录</li>
</ul>
<p>打开浏览器访问对应目录下的index.html即可访问本地文档。</p>

<h2>如何书写PaddlePaddle的文档<a class="headerlink" href="#id4" title="永久链接至标题">¶</a></h2>
<p>PaddlePaddle文档使用 <a class="reference external" href="http://www.sphinx-doc.org/en/1.4.8/">sphinx</a> 自动生成，用户可以参考sphinx教程进行书写。</p>
</div>

<h2>如何更新www.paddlepaddle.org文档<a class="headerlink" href="#www-paddlepaddle-org" title="永久链接至标题">¶</a></h2>
<p>开发者给PaddlePaddle代码增加的注释以PR的形式提交到github中，提交方式可参见 <a class="reference external" href="http://doc.paddlepaddle.org/develop/doc_cn/howto/dev/contribute_to_paddle_cn.html">贡献文档</a> 。
目前PaddlePaddle的develop分支的文档是自动触发更新的，用户可以分别查看最新的 <a class="reference external" href="http://doc.paddlepaddle.org/develop/doc_cn/">中文文档</a> 和
<a class="reference external" href="http://doc.paddlepaddle.org/develop/doc/">英文文档</a> 。</p>
