 ## 生成补全脚本
 
-在 `build.rs` 中调用 `build_comp_scripts` 生成补全脚本（需要 `builds` + `comp` 特性）。
+开启 `comp` 特性后，`gen_program!()` 会在编译期自动调用 `build_comp!()`，生成以 `CARGO_PKG_NAME` 命名的补全脚本到 `target/mingling/`。
+
+如果你的二进制名与 crate 名不同，可以手动调用 `build_comp!()` 并指定二进制名：
 
+```rust
+// Features: ["comp"]
+@@@use mingling::macros::build_comp;
+@@@fn example() {
+build_comp!("mybin");
+@@@}
