+# 预设特性组
+
+Mingling 提供了一系列**预设特性组**，方便用户按需组合启用特性。
+
+## `mini`
+
+**启用特性：** `extras`、`picker`
+
+**定位：** 精简模式，适合小型 CLI 工具或需要快速起步的项目。仅包含最核心的便捷宏和参数解析能力。
+
+## `advanced`
+
+**启用特性：** `extras`、`picker`、`repl`、`comp`、`dispatch_tree`、`structural_renderer`
+
+**定位：** 进阶模式，在 `mini` 的基础上加入了交互式 REPL 环境、代码补全、调度树加速以及基础的结构化输出能力，适合功能较完整的中型命令行应用。
+
+## `full`
+
+**启用特性：** `extras`、`picker`、`repl`、`clap`、`comp`、`dispatch_tree`、`structural_renderer_full`、`pathf`
+
+**定位：** 完整模式，启用 Mingling 的全部核心功能。在 `advanced` 的基础上额外包含 clap 集成、完整的结构化渲染器（含所有序列化格式）以及实验性的路径分析器，适合大型、功能全面的命令行应用。
+
+## `build_advanced`
+
+**启用特性：** `build`、`comp`
+
+**定位：** 构建期增强配置，用于在项目构建时生成补全脚本等构建辅助材料（`comp` 特性提供补全脚本生成能力）。

+# Preset Feature Groups
+
+Mingling provides a set of **preset feature groups** that make it easy to enable features in whatever combination you need.
+
+## `mini`
+
+**Enables features:** `extras`, `picker`
+
+**Positioning:** Minimal mode, suitable for small CLI tools or projects that need to get started quickly. Includes only the most essential convenience macros and argument parsing capabilities.
+
+## `advanced`
+
+**Enables features:** `extras`, `picker`, `repl`, `comp`, `dispatch_tree`, `structural_renderer`
+
+**Positioning:** Advanced mode, builds on `mini` by adding an interactive REPL environment, code completion, dispatch tree acceleration, and basic structured output capabilities. Suitable for medium-sized command-line applications with a fuller feature set.
+
+## `full`
+
+**Enables features:** `extras`, `picker`, `repl`, `clap`, `comp`, `dispatch_tree`, `structural_renderer_full`, `pathf`
+
+**Positioning:** Full mode, enables all of Mingling's core functionality. In addition to `advanced`, it includes clap integration, the full structural renderer (with all serialization formats), and the experimental path analyzer. Suitable for large, feature-complete command-line applications.
+
+## `build_advanced`
+
+**Enables features:** `build`, `comp`
+
+**Positioning:** Build-time enhanced configuration, used to generate build helpers such as completion scripts at build time (the `comp` feature provides completion script generation).
+
+> [!NOTE]
+>
+> This feature group is intended for **build dependencies** only and must be used alongside the `advanced` feature. Enable it in the `[build-dependencies]` section of `Cargo.toml`:
+
+```toml
+[dependencies.mingling]
+features = ["advanced"]
+ 
+[build-dependencies.mingling]
+features = ["build_advanced"]
+```
+ 
+## `build_full`
+
+**Enables features:** `build`, `comp`, `pathf`, `dispatch_tree`
+
+**Positioning:** Full build-time configuration, extends `build_advanced` with the path analyzer (`pathf`) to automatically resolve type module paths, suitable for projects with complex structures that require automated build-time analysis.
+
+> [!NOTE]
