+    A hands-on guide to resources

+
+Resources are Mingling's mechanism for managing global state. Any type that implements `Default + Clone` can be a resource.
+
+## Define a Resource
+
+```rust
+// Any type implementing Default + Clone can be used as a resource
+#[derive(Default, Clone)]
+struct ResCurrentDir(String);
+ 
+// Register with the Program
+fn main() {
+    let mut program = ThisProgram::new();
+    program.with_resource(ResCurrentDir(".".into()));
+    program.exec_and_exit();
+}
+```
+ 
+Since `ResCurrentDir` implements both `Default` and `Clone`, the framework automatically implements `ResourceMarker` for it — no manual impl needed.
+
+## Inject & Use
+
+In a Chain or Renderer, simply declare the resource in the parameter list:
+
+```rust
+@@@#[derive(Default, Clone)]
+@@@struct ResCurrentDir(String);
+@@@dispatcher!("pwd", CMDPrintWorkingDir => EntryPrintWorkingDir);
+@@@pack!(ResultPath = String);
+// Inject read-only resource via &T
+#[chain]
+fn handle_pwd(_args: EntryPrintWorkingDir, cwd: &ResCurrentDir) -> Next {
+    ResultPath::new(cwd.0.clone()).to_render()
+}
+ 
+#[renderer]
+fn render_path(result: ResultPath) {
+    r_println!("{}", *result);
+}
+```
+ 
+## Modify a Resource
+
+Use `&mut T` to inject a mutable resource:
+
+```rust
+@@@#[derive(Default, Clone)]
+@@@struct ResVisitCount(u32);
+@@@dispatcher!("visit", CMDVisit => EntryVisit);
+@@@pack!(ResultDone = ());
+#[chain]
+fn handle_visit(_args: EntryVisit, counter: &mut ResVisitCount) -> Next {
+    counter.0 += 1;
+    ResultDone::default()
+}
+ 
+#[renderer]
+fn render_done(_done: ResultDone, counter: &ResVisitCount) {
+    r_println!("visit count is : {}", counter.0);
+}
+```
+ 
+## Use Multiple Resources
+
+A Chain can inject any number of resources at once — the framework matches them by type automatically:
+
+```rust
+@@@#[derive(Default, Clone)] struct ResConfig(String);
+@@@#[derive(Default, Clone)] struct ResCounter(u32);
+@@@dispatcher!("test", CMDTest => EntryTest);
+@@@pack!(ResultDone = ());
+// Inject both read-only and mutable resources
+#[chain]
+fn handle_test(_args: EntryTest, config: &ResConfig, counter: &mut ResCounter) -> Next {
+    println!("config: {}", config.0);
+    counter.0 += 1;
+    ResultDone::default().to_render()
+}
+```
+
