 <p>If you are adding a new language type, you can create a new directory under the <code>/web/src/pages/Doc/</code> directory, Then create a folder for each chapter, You can also directly copy all chapter directories under the existing language directory for translation, Note that you only need to write the <code>index.md</code> file, The <code>index.vue</code> file under the chapter directory is automatically generated by the script according to <code>index.md</code>.</p>
