+Fix: 1.Fixed an issue where the default value of the zoom center point was not updated after changing the canvas size.
+
+## 0.6.4
+
+New: 1.The default is to scale at the center point of the canvas. 2.Optimize the scaling of both fingers on the mobile end, with the center position of the two fingers as the center point for scaling.
+
+## 0.6.3
+
+Fix: 1.Fix the issue where the summary node will respond to inserting node shortcuts.
+
+New: 1.Support custom node content.

+# 如何自定义节点内容
+
+> 该特性v0.6.3+版本支持
+
+如果你想自定义节点的内容，那么可以在实例化`simple-mind-map`时传入以下选项：
+
+```js
+new MindMap({
+    isUseCustomNodeContent: true,
+    customCreateNodeContent: (node) => {
+        // return你的自定义DOM节点
+    }
+})
+```
+
+`customCreateNodeContent`方法会接收当前遍历到的节点实例作为参数，一般而言你会需要该节点的数据，这可以通过如下方式获取：
+
+```js
+node.nodeData.data
+```
+
+其他节点实例属性你可以自行打印出来看看。
+
+`customCreateNodeContent`方法需要返回`DOM`节点，如果某个节点你不想自定义，那么可以返回`null`，那么还是会走内置的节点渲染逻辑。
+
+返回的`DOM`节点的宽高需要是确定的，如果是动态的那么会导致宽高获取错误，最终导致节点定位错误和发生重叠等问题。
+
+如果使用了自定义节点内容，那么内置的插入节点内容的相关方法你都不应该再使用，因为相当于整个节点内容都由你自己控制，另外，节点样式设置也不会再生效，切换主题也只会切换非节点内容的样式，最后，双击节点也不会再进入编辑，所以这个功能一般用于展示性的需求。
+
+## 示例1：渲染自定义DOM节点
+
+```js
+{
+    customCreateNodeContent: (node) => {
+        let div = document.createElement('div')
+        div.className = 'xxx'
+        div.style.cssText = `xxx`
+        div.innerHTML = `
+            <h1>我是自定义节点</h1>
+            ${ node.nodeData.text }
+        `
+        return div
+    }
+}
+```
+
+## 示例2：渲染Vue2组件
+
+如果想要使用一个相对简单的`Vue`组件，那么可以通过如下方式：
+
+```js
+import CustomNodeContent from 'CustomNodeContent.vue'
+import Vue from 'vue'
+
+{
+    customCreateNodeContent: (node) => {
+        let el = document.createElement('div')
+        let Comp = Vue.extend(CustomNodeContent)
+        let comp = new Comp({
+            // props
+            propsData: {
+                html: node.nodeData.data.text
+            }
+        })
+        comp.$mount(el)
+        return comp.$el
+    }
+}
+```
+
+如果你的`Vue`组件比较复杂，里面用到了`vueRouter`、`vuex`、`i18n`等，那么要和你项目的入口组件一样，在实例化时要把这些内容也加载到组件内，不然会报错。
+
+```js
+import CustomNodeContent from 'CustomNodeContent.vue'
+import Vue from 'vue'
+import router from './router'
+import store from './store'
+import i18n from './i18n'
+
+{
+    customCreateNodeContent: (node) => {
+        let el = document.createElement('div')
+        let Comp = Vue.extend(CustomNodeContent)
+        let comp = new Comp({
+            // props
+            propsData: {
+                html: node.nodeData.data.text
+            },
+            router,
+            store,
+            i18n
+        })
+        comp.$mount(el)
+        return comp.$el
+    }
+}
+```
+
+## 示例3：渲染Vue3组件
+
+```js
+import { createApp } from "vue"
+import CustomNodeContent from './CustomNodeContent.vue'
+
+{
+    customCreateNodeContent: (node) => {
+        let el = document.createElement('div')
+        const app = createApp(CustomNodeContent, {// props
+            html: node.nodeData.data.text
+        })
+        app.mount(el)
+        return el
+    }
+}
+```
+
+## 示例4：渲染react组件
+
+如果你成功渲染了`react`组件，欢迎[提交](https://github.com/wanglin2/mind-map/issues/new)示例代码给我~
