+### How to add custom content when exporting
+
+The two instantiation options `addContentToHeader` and `addContentToFooter` can be used to add custom content at the beginning and end when exporting `png`、`svg`、`pdf`, The default value is `null`, which means no configuration. A function can be passed and can return `null`, which means no content will be added. If you want to add content, you need to return the following structure:
+
+```
+{
+  el,// Custom DOM node to be added, styles can be inline
+  cssText,// Optional, if the style does not want to be inlined, you can pass this value as a CSS string
+  height: 50// The height of the returned DOM node must be passed
+}
+```
+
+A simple example:
+
+```js
+new MindMap({
+  addContentToFooter: () => {
+    const el = document.createElement('div')
+    el.className = 'footer'
+    el.innerHTML = 'From: simple-mind-map'
+    const cssText = `
+      .footer {
+        width: 100%;
+        height: 30px;

+    return {
