+//! `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();
+}
+
+dispatcher!("setup", SetupCommand => SetupEntry);
+pack!(StateRead = ());
+pack!(ResultCurrentDir = PathBuf);
+
+#[chain]
+fn setup(
+    _prev: SetupEntry,
+    resource: &mut MyResource, // Import the resource into `setup`
+) -> NextProcess {
+    // Set the global resource
+    resource.current_dir = current_dir().unwrap();
+
+    StateRead::default()
+}
+
+#[chain]
+fn read(_prev: StateRead, resource: &MyResource) -> NextProcess {
+    // Read the global resource
+    let current_dir = resource.current_dir.clone();
+    ResultCurrentDir::new(current_dir).to_render()
+}
