+## 初始化
\ No newline at end of file
+
+```
+pip install -r requirement.txt
+```
+
+
+## 目录结构说明
+
+* 技能树`骨架文件`：
+    * 位置：`data/tree.json` 
+    * 说明：该文件是执行 `python main.py` 生成的，请勿人工编辑
+* 技能树`根节点`配置文件：
+    * 位置：`data/config.json`
+    * 说明：可编辑配置关键词等字段，其中 `node_id` 字段是生成的，请勿编辑
+* 技能树`难度节点`：
+    * 位置：`data/xxx`，例如: `data/1.Java初阶`
+    * 说明：
+        * 每个技能树有 3 个等级，目录前的序号是必要的，用来保持文件夹目录的顺序
+        * 每个目录下有一个 `config.json` 可配置关键词信息，其中 `node_id` 字段是生成的，请勿编辑
+* 技能树`章节点`：
+    * 位置：`data/xxx/xxx`，例如：`data/1.Java初阶/1.Java概述`
+    * 说明：
+        * 每个技能树的每个难度等级有 n 个章节，目录前的序号是必要的，用来保持文件夹目录的顺序
+        * 每个目录下有一个 `config.json` 可配置关键词信息，其中 `node_id` 字段是生成的，请勿编辑
+* 技能树`知识节点`：
+    * 位置：`data/xxx/xxx/xxx`，例如：`data/1.Java初阶/1.Java概述/1.什么是Java`
+    * 说明：
+        * 每个技能树的每章有 `n` 个知识节点，目录前的序号是必要的，用来保持文件夹目录的顺序
+        * 每个目录下有一个 `config.json`
+            * 其中 `node_id` 字段是生成的，请勿编辑
+            * 其中 `keywords` 可配置关键字字段
+            * 其中 `children` 可配置该`知识节点`下的子树结构信息，参考后面描述
+            * 其中 `export` 可配置该`知识节点`下的导出习题信息，参考后面描述
+
+
+## `知识节点` 子树信息结构
+
+例如 `data/1.Java初阶/1.Java概述/1.什么是Java/config.json` 里配置对该知识节点子树信息结构：
+```json
+{
+    // ...
+
+    "children": [
+        // TODO ...
+    ],
+}
+```
+
+
+
+## `知识节点` 的导出习题编辑
+
+例如 `data/1.Java初阶/1.Java概述/1.什么是Java/config.json` 里配置对该知识节点导出的习题
+
+```json
+{
+    // ...
+    "export": [
+        // TODO ...
+    ]
+}
+```
+
+格式说明：
+* `file`: 指定该目录下的习题源文件
+* `variants`： 指定习题同名的json选项配置文件，参考下一节
+* `depends`: 如果习题依赖同目录下的其他习题源代码，则在此字段里配置依赖的其他习题源文件名
+
+## `知识节点` 的导出习题选项配置编辑
+
+首先，在知识节点下增加一个习题代码，例如在 `data/1.Java初阶/1.Java概述/1.什么是Java` 下增加一个`HelloWorld.java`代码：
+
+```java
+// TODO
+```
+
+其次，增加一个同名的选项配置文件`HelloWorld.json`，目前有两种配置规则
+
+**单行替换规则**：
+
+* 配置由`one_line`字段指定的单行替换字典
+* 格式是：`"<源字符串>"`: [`"<替换字符串A>"`, `<替换字符串B>`,...],
+    * 其中每个 `"<源字符串>"` `/` `"<替换字符串A>"` 被生成为是一个替换选项
+    * 指定的配置应该能至少生成 `3+` 个替换选项
+
+```json
+{
+    // TODO
+}
+```
+
+上面的替换规则会将代码替换成 3 个变种的代码：
+
+```c
+// 变种代码1
+// TODO
+```
+
+```c
+// 变种代码2
+#include <stdio.h>
+int main(int argc, char** argv){
+    print("Hello,Wrold!");
+    return 0
+}
+```
+
+```c
+// 变种代码3
+// TODO
+```
+
+这些变种代码将会作为技能树该知识点该代码选择题的选项。
+
+**多行替换规则**：
+
+* 配置由`multiline`字段指定的多行替换数组
+* 数组的每个元素是一组替换规则，会整组被替换
+
+例如：
+
+```json
+{
+     // TODO
+}
+```
+
+同样，该配置将支持将源代码生成3个变种代码
+
+```java
+// 变种代码1
+// TODO
+```
+
+```java
+// 变种代码2, 注意第2组替换规则，包含了两行替换
+// TODO
+```
+
+```java
+// 变种代码3
+// TODO
+```
+
+## 技能树合成
+
+在根目录下执行 `python main.py` 会合成技能树文件，合成的技能树文件: `data/tree.json`
+* 合成过程中，会自动检查每个目录下 `config.json` 里的 `node_id` 是否存在，不存在则生成
+* 合成过程中，会自动检查每个知识点目录下 `config.json` 里的 `export` 里导出的习题配置，检查是否存在`exercise_id` 字段，如果不存在则生成
