+//! `Mingling` Example - Global Resource Injection
+//!
+//! This example demonstrates how to use global resource injection in `#[chain]` functions.
+//! You can inject both immutable (`&T`) and mutable (`&mut T`) references to global resources.
+//!
+//! # How to Run
+//! ```bash
+//! cargo run --manifest-path ./examples/example-resources/Cargo.toml -- setup
+//! ```
+
+use mingling::prelude::*;
+use std::{env::current_dir, path::PathBuf};
+
+// Define a resource for storing global state
+#[derive(Default, Clone)]
+pub struct MyResource {
+    current_dir: PathBuf,
+}
+
+fn main() {
+    let mut program = ThisProgram::new();
+
+    // Add the resource to the program
+    program.with_resource(MyResource::default());
+
+    program.with_dispatcher(SetupCommand);
+    program.exec_and_exit();
+}
