+
+> 一个简单&强大的Web思维导图
+
+本项目包含两部分：
+
+1.一个 js 思维导图库，不依赖任何框架，你可以使用它来快速完成 Web 思维导图产品的开发。
+
+开发文档：[https://wanglin2.github.io/mind-map/#/doc/zh/](https://wanglin2.github.io/mind-map/#/doc/zh/)。
+
+2.一个 Web 思维导图，基于思维导图库、Vue2.x、ElementUI 开发，可以操作电脑本地文件，所以你可以直接把它当做一个在线版思维导图应用使用，如果觉得 github 的响应速度慢，你也可以部署到你的服务器上。
+
+在线地址：[https://wanglin2.github.io/mind-map/](https://wanglin2.github.io/mind-map/)。
+
+另外也提供了客户端可供下载使用，支持`Windows`、`Mac`及`Linux`，下载地址：
+
+Github：[releases](https://github.com/wanglin2/mind-map/releases)。

+
+# 特性
+
+- [x] 插件化架构，除核心功能外，其他功能作为插件提供，按需使用，减小打包体积
+- [x] 支持逻辑结构图、思维导图、组织结构图、目录组织图、时间轴（横向、竖向）、鱼骨图等结构
+- [x] 内置多种主题，允许高度自定义样式，支持注册新主题
+- [x] 节点内容支持文本（普通文本、富文本）、图片、图标、超链接、备注、标签、概要
+- [x] 节点支持拖拽（拖拽移动、自由调整）、多种节点形状，支持使用 DDM 完全自定义节点内容
+- [x] 支持画布拖动、缩放
+- [x] 支持鼠标按键拖动选择和Ctrl+左键两种多选节点方式
+- [x] 支持导出为`json`、`png`、`svg`、`pdf`、`markdown`、`xmind`，支持从`json`、`xmind`、`markdown`导入
+- [x] 支持快捷键、前进后退、关联线、搜索替换、小地图、水印
+- [x] 提供丰富的配置，满足各种场景各种使用习惯
+
+# 安装
+
+```bash
+npm i simple-mind-map
+```
+
+# 使用
+
+提供一个宽高不为0的容器元素：
+
+```html
+<div id="mindMapContainer"></div>
+```
+
+另外再设置一下`css`样式：
+
+```css
+#mindMapContainer * {
+  margin: 0;
+  padding: 0;
+}
+```
+
+然后创建一个实例：
+
+```js
+import MindMap from "simple-mind-map";
+
+const mindMap = new MindMap({
+  el: document.getElementById('mindMapContainer'),
+  data: {
+    "data": {
+        "text": "根节点"
+    },
+    "children": []
+  }
+});
+```
+
+即可得到一个思维导图。
