[Git-flow] Hi @MeteorsLiu, There are some suggestions for your information:

---

Rebase suggestions

• Following commits seems generated via git merge

  Merge branch 'main' of https://github.com/goplus/llcppg into trie

Which seems insignificant, recommend to use git rebase command to reorganize your PR.

For other git-flow instructions, recommend refer to these examples.

为了实现设计驱动，我倾向于我们应该先产出设计文档。我的建议目录结构如下：

第一层是语言，视为文档的根：

• doc/zh/...
• doc/en/...

根目录默认只放用户使用相关，如 quickstart 之类。

llccpg 开发者相关的放到 doc/zh/dev 子目录下。我们之前已经提供的文档 https://github.com/goplus/llcppg/blob/main/doc/llcppg.md 应该主要是面向开发者的，当然开头部分有面向用户的部分，可以分拆一下。
