+### View Learning Progress
+
+> Read-only progress overview grouped by chapter, without entering practice mode
+
+```bash
+d2x status
+```
+
+### Native Mode (optional)
+
+> Every C++ standard directory is a real mcpp project and the exercises are its tests/ — you can practice with plain mcpp, no d2x involved:
+
+```bash
+mcpp test -p src/en/cpp11              # progress table for the whole cpp11 section
+mcpp test -p src/en/cpp11 03-trailing  # run only exercises matching the name
+```
+
 ### Sync Latest Practice Code
 
-> Since the project is continuously updated, you can use the following command for automatic synchronization (if synchronization fails, you may need to manually update the project code using git)
+> The project is continuously updated; update via git (save/commit your modified exercises first):
 
 ```bash
-d2x update
+git pull
 ```

+### 原生模式(可选)
+
+> 每个 C++ 标准目录都是真实的 mcpp 工程,练习就是它的 tests/——不经过 d2x,直接用 mcpp 也能练:
+
+```bash
+mcpp test -p src/cpp11              # 整个 cpp11 的进度表(哪题绿哪题红)
+mcpp test -p src/cpp11 03-trailing  # 只跑名字匹配的练习
+```

 ### 同步最新的练习代码
 
-> 由于项目处于持续更新阶段, 可以使用下面的命令进行自动同步(如果同步失败, 可能需要手动用git进行更新项目代码)
+> 项目处于持续更新阶段,更新使用 git(注意先保存/提交你已修改的练习):
 
 ```bash
-d2x update
+git pull
 ```
