+```
+
+After registration and instantiation of `MindMap`, the instance can be obtained through `mindMap.associativeLine`.
+
+## Config
+
+Support for modifying the thickness and color of associated lines, divided into default and active states. The configuration is as follows:
+
+- `associativeLineWidth`: The thickness of the default state of the associated line. The default value is `2`
+
+- `associativeLineColor`: Color of the default state of associative lines. The default value is `rgb(51, 51, 51)`
+
+- `associativeLineActiveWidth`: The thickness of the active state of the associated line. The default value is `8`
+
+- `associativeLineActiveColor`: The color of the active state of the associated line. The default value is `rgba(2, 167, 240, 1)`
+
+The configuration is provided as a theme, so if you want to modify these four properties, you can modify them using the `mindMap.setThemeConfig(config)` method.
+
+## Props
+
+### mindMap.associativeLine.lineList
+
+Currently, all connection line data, array types, and each item of the array are also an array:
+
+```js
+[
+    path, // Connector node
+    clickPath, // Invisible click line node
+    node, // Start node
+    toNode // Target node
+]
+```
+
+### mindMap.associativeLine.activeLine
+
+The currently active connection line and array type are the same as the structure of each item in the `lineList` array.
+
+## Methods
+
+### renderAllLines()
+
+Re-render all associated lines.
+
+### removeAllLines()
+
+Remove all associated lines.
+
+### createLineFromActiveNode()
+
+Create an associated line from the current active node. If there are multiple active nodes, the default is the first node.
+
+After calling this method, an association line will be rendered from the first active node to the current mouse real-time position. When a target node is clicked, it represents completion of creation. An association line will be rendered between the first active node and the clicked node.
+
+### createLine(fromNode)
+
+Creates an associative line starting at the specified node.
+
+After calling this method, an association line will be rendered from the specified node to the current mouse real-time position. When a target node is clicked, it represents completion of creation, and an association line will be rendered between the specified node and the clicked node.
+
+### addLine(fromNode, toNode)
+
+Add an associative line directly.
+
+Calling this method will directly create an association line from the `fromNode` to the `toNode` node.
+
+### removeLine()
+
+Deletes the currently active associative line. Clicking on an associated line is considered active.
+
+### clearActiveLine()
+
+Clears the active state of the currently active association line.

 # Changelog

+## 0.4.7
+
+optimization: 1.During rich text editing, when initially focusing, all are no longer selected by default; 2.When editing rich text, use the node fill color as the background color to avoid being invisible when the node color is white.  3.Node activation state switching no longer triggers history. 4.Triggering history multiple times in a short time will only add the last data. 5.Optimize the addition of historical records. When there is a rollback, delete the historical data after the current pointer when adding a new record again.
+
+New: 1.Support for importing and exporting Markdown format files. 2.Support for configuring initial text when inserting nodes. 3.Expand the commands for inserting and deleting nodes to support specifying nodes.
+
+## 0.4.6
+
+New: 1.Associated lines support adjusting control points.
+
+optimization: 1.When adding historical data, filter data that has not changed compared to the previous time.
+
+Fix: 1.Fixed a conflict between the direction keys and the navigation function of the direction keys during node editing. 2.Fixed the issue of node id loss when dragging a mobile node, which can cause associated lines to be lost.
+
+## 0.4.5
+
+New: 1.Supports associative lines. 2.You can also drag the canvas by holding down the root node. 3. Hold down the ctrl key to adjust multiple selected nodes.
+
+## 0.4.4
+
+New: Support horizontal scrolling in response to the mouse.
+
 ## 0.4.3

 Fix: No trigger after forward and backward `data_ Change` event.

+# Markdown parse
+
+> v0.4.7+
+
+Provides methods for importing and exporting `Markdown` files.
+
+## Import
+
+```js
+import markdown from 'simple-mind-map/src/parse/markdown.js'
+```
+
+If you are using the file in the format of `umd`, you can obtain it in the following way:
+
+```html
+<script src="simple-mind-map/dist/simpleMindMap.umd.min.js"></script>
+```
+
+```js
+MindMap.markdown
+```
+
+## Methods
+
+### transformToMarkdown(data)
+
+- `data`: Mind map data can be obtained using the `mindMap.getData()` method.
+
+Convert mind map data into `Markdown` format data, and the returned data is a string.
+
+### transformMarkdownTo(mdContent)
+
+- `mdContent`: The `Markdown` data to convert, string type.
+
+Convert the `Markdown` string into node tree data and return a `Promise` instance. You can use the `mindMap.setData()` method to render the converted data onto the canvas.

+# AssociativeLine 插件
+
+> v0.4.5+
+
+> 调整关联线控制点的功能从v0.4.6+开始支持
+
+该插件用于支持添加关联线。
+
+该插件目前功能还不完善，不支持在关联线上添加文字。
+
+## 注册
+
+```js
+import MindMap from 'simple-mind-map'
+import AssociativeLine from 'simple-mind-map/src/AssociativeLine.js'
+
+MindMap.usePlugin(AssociativeLine)
+```
+
+注册完且实例化`MindMap`后可通过`mindMap.associativeLine`获取到该实例。
+
+## 配置
+
+支持修改关联线的粗细和颜色，分为默认状态和激活状态。配置如下：
+
+- `associativeLineWidth`：关联线默认状态的粗细，默认值为`2`
+
+- `associativeLineColor`：关联线默认状态的颜色，默认值为`rgb(51, 51, 51)`
+
+- `associativeLineActiveWidth`：关联线激活状态的粗细，默认值为`8`
+
+- `associativeLineActiveColor`：关联线激活状态的颜色，默认值为`rgba(2, 167, 240, 1)`
+
+配置以主题的方式提供，所以如果想要修改这四个属性，可以通过`mindMap.setThemeConfig(config)`方法进行修改。
+
+## 属性
+
+### mindMap.associativeLine.lineList
+
+当前所有连接线数据，数组类型，数组的每一项也是一个数组：
+
+```js
+[
+    path, // 连接线节点
+    clickPath, // 不可见的点击线节点
+    node, // 起始节点
+    toNode // 目标节点
+]
+```
+
+### mindMap.associativeLine.activeLine
+
+当前激活的连接线，数组类型，同`lineList`数组的每一项的结构。
+
+## 方法
+
+### renderAllLines()
+
+重新渲染所有关联线。
+
+### removeAllLines()
+
+移除所有关联线。
+
+### createLineFromActiveNode()
+
+从当前激活节点开始创建关联线，如果有多个激活节点，默认为第一个节点。
+
+调用该方法后，会从第一个激活节点到当前鼠标实时位置渲染一条关联线，当点击某个目标节点后则代表创建完成，会在第一个激活节点和点击节点之间渲染一条关联线。
+
+### createLine(fromNode)
+
+从指定节点开始创建关联线。
+
+调用该方法后，会从指定节点到当前鼠标实时位置渲染一条关联线，当点击某个目标节点后则代表创建完成，会在指定节点和点击节点之间渲染一条关联线。
+
+### addLine(fromNode, toNode)
+
+直接添加一条关联线。
+
+调用该方法，会直接创建一条从`fromNode`到`toNode`节点的关联线。
+
+### removeLine()
+
+删除当前激活的关联线。点击某条关联线则视为激活。
+
+### clearActiveLine()
+
+清除当前激活的关联线的激活状态。

 # Changelog

+## 0.4.7
+
+优化：1.富文本编辑时初始聚焦时不再默认全选；2.富文本编辑时使用节点填充色作为背景色，避免节点颜色为白色时看不见。 3.节点激活状态切换不再触发历史记录。 4.短时间多次触发历史记录，只会添加最后一次的数据。 5.优化历史记录添加，当有回退时，再次添加新记录时删除当前指针后面的历史数据。 
+
+新增：1.支持导入和导出Markdown格式文件。 2.支持配置插入节点时的初始文字。 3.扩展插入节点和删除节点的命令，支持指定节点。
+
+## 0.4.6
+
+新增：1.关联线支持调整控制点。
+
+优化：1.添加历史数据时过滤和上一次相比没有改变的数据。
+
+修复：1.修复节点编辑时方向键和方向键导航功能的冲突问题。 2.修复拖拽移动节点时节点id的丢失问题，这会导致关联线丢失。
+
+## 0.4.5
+
+新增：1.支持关联线。 2.按住根节点也可以拖动画布。3.按住ctrl键可以调整多选节点。
+
+## 0.4.4
+
+新增：支持响应鼠标的横向滚动。
+
 ## 0.4.3

 修复：前进回退后没有触发`data_change`事件的问题。

+# Markdown解析
+
+> v0.4.7+
+
+提供导入和导出`Markdown`文件的方法。
+
+## 引入
+
+```js
+import markdown from 'simple-mind-map/src/parse/markdown.js'
+```
+
+如果使用的是`umd`格式的文件，那么可以通过如下方式获取：
+
+```html
+<script src="simple-mind-map/dist/simpleMindMap.umd.min.js"></script>
+```
+
+```js
+MindMap.markdown
+```
+
+## 方法
+
+### transformToMarkdown(data)
+
+- `data`：思维导图数据，可以通过`mindMap.getData()`方法获取。
+
+将思维导图数据转换成`Markdown`格式数据，返回的是字符串。
+
+### transformMarkdownTo(mdContent)
+
+- `mdContent`：要转换的`Markdown`数据，字符串类型。
+
+将`Markdown`字符串转换成节点树数据，返回一个`Promise`实例。可以使用`mindMap.setData()`方法将转换后的数据渲染到画布上。
