+#### homepage
+
+`README.md` will be render as homepage for your website in docs folder, but sometimes we want to specify another file as a homepage, or even use the `README.md` in your repo. we can use:
+
+```html
+<script src="/lib/docsify.js" data-homepage="https://raw.githubusercontent.com/QingWei-Li/docsify/master/README.md"></script>
+<!-- Or using `Welcome.md` as homepge -->
+<script src="/lib/docsify.js" data-homepage="Welcome.md"></script>
+```
+
+
+#### basePath
+
+If your HTML entry file and the markdown files are in different directories, we can use:
+
+```html
+<script src="/lib/docsify.js" data-base-path="/base/"></script>
+
+<!-- Even if the docs is on another site 😄 -->
+<script src="/lib/docsify.js" data-base-path="https://docsify.js.org/"></script>

+#### homepage
+
+默认情况下网站会将根目录下 `README.md` 作为首页渲染，但是有些时候我们想指定其他文件，甚至想直接将 repo 下的 README 作为首页。你可以这样做：
+
+
+```html
+<script src="/lib/docsify.js" data-homepage="https://raw.githubusercontent.com/QingWei-Li/docsify/master/README.md"></script>
+<!-- 或者将 Welcome.md 作为首页 -->
+<script src="/lib/docsify.js" data-homepage="Welcome.md"></script>
+```
+
+#### basePath
+
+指定加载文档的路径，如果你的 HTML 入口文件和文档是放在不同地方，你可以设置：
+
+```html
+<script src="/lib/docsify.js" data-base-path="/base/"></script>
+
+<!-- 甚至文档是在其他站点下 😄 -->
+<script src="/lib/docsify.js" data-base-path="https://docsify.js.org/"></script>
