+
+If you're troubled by these issues —
+
+1. Too many subcommands make `main.rs` bloat rapidly;
+2. Handler logic mixed with side effects;
+3. Logging, auth, and other cross-cutting concerns are hard to inject non-invasively;
+4. Maintaining shell completion scripts for multiple platforms wears you out;
+5. Global resources everywhere, making testing difficult.
+
+… then you've come to the right place.
+
+Of course, if you're just curious about "how to write maintainable CLIs in Rust," you've also come to the right place — it'll be fun.
+
+## What is Mingling?
+
+> **Mìng Lìng** is the pinyin of the Chinese word **命令**,
+> which translates to **Command** in English.
+
+Mingling is a CLI framework built with Rust. It's free, open-source, and licensed under the permissive MIT / Apache 2.0 license.
+
+Mingling's design goals:
+
+- **Extensible**: From 3 subcommands to 30, same pattern, no framework swap
+- **Decoupled**: Parse args once, write business logic once, define output format once. Each independent.
+- **Type-driven**: Clear, typed data flows through the pipeline — not `Vec<String>`
+- **Lightweight deps**: Minimal core deps, low cost to pull in; advanced features on demand, no compile-time drag
+- **Efficient**: Dispatch logic generated at compile time, no unnecessary runtime overhead

+Alright, wanna give it a try?
