If you need to modify the code yourself, you can use this method.</li> <li>Installation from binary files. Download the binary files from the official website. This is the recommended method, in which you will get a binary released package which is out-of-the-box.(Comming Soon...)</li></ul> <p>Here in the Quick Start, we give a brief introduction of using source code to install IoTDB. For further information, please refer to Chapter 4 of the User Guide.</p> <h3 id="installation-from-source-code"><a href="#installation-from-source-code" class="header-anchor">#</a> Installation from source code</h3> <p>You can get the released source code from https://iotdb.apache.org/Download/, or from the git repository https://github.com/apache/incubator-iotdb/tree/master</p> <p>Now suppose your directory is like this:</p> <div class="language- line-numbers-mode"><pre class="language-text"><code>&gt; pwd

</code></pre> <div class="line-numbers-wrapper"><span class="line-number">1</span><br><span class="line-number">2</span><br></div></div><p>Then under the root path of incubator-iotdb, you can build IoTDB using Maven:</p> <div class="language- line-numbers-mode"><pre class="language-text"><code>&gt; pwd
