-    <h2 id='什么是vvd'>What is VVD</h2>
-    <p>VVD is a file under the same path as .ddb and .ddi files, using the same name as .ddb and .ddi files, storing the basic information about the voicebank.</p>
-    <h2 id='编辑vvd可以干什么'>What can we do by editing VVD</h2>
-    <p>Editing <code>VOICENAME</code> in VVD can change the name of a voicebank in V2/3/4 editor. (V5 editor reads the name string in registry and won't be affected.)</p>
-    <h2 id='关于如何使用安装脚本'>How to use the install script</h2>
-    <p>This script can install a voicebank into V4</p>
-    <ol start=''>
-        <li>Fill in the CompID and the name of a voicebank, download the.vvd file and the script.</li>
-        <li>Move the .ddb, .ddi, and .vvd file under a subdir whose name is same as the <code>CompID</code> of this voicebank. (E.g. Luotianyi_CHN_Meng: <code>D:\Program Files
-            (x86)\VoiceDB\LuoTianyiV4_CHN\BK8H76TAEHXWSKDB</code>) Confirm .ddb, .ddi and .vvd files share the same name and under the same dir.
-        </li>
-        <li>Move <code>install.bat</code> into the same dir as above and <strong>Run as Administrator</strong>.
-        </li>
-        <li>Now the voicebank should have been successfully installed. Similarly, you can uninstall it using <code>uninstall.bat</code>.</li>
-
-    </ol>
-    <h2 id='关于compid'>About CompID</h2>
-    <p>
-        Since the install script is for V4, you need to get a CompID for the voicebank which matches its language. V4 voicebanks can directly use the origin CompID. V5 voicebanks, however, need to get a corresponding V4 CompID. Here are some V4 CHN CompID and V4 JPN CompID, click to pick it randomly.
