+The example below shows how to use `Mingling` to create a simple CLI program:
+
+```rust
+use mingling::macros::{dispatcher, gen_program, r_println, renderer};
+
+fn main() {
+    let mut program = ThisProgram::new();
+    program.with_dispatcher(HelloCommand);
+
+    // Execute
+    program.exec();
+}
+
+// Define command: "<bin> hello"
+dispatcher!("hello", HelloCommand => HelloEntry);
+
+// Render HelloEntry
+#[renderer]
+fn render_hello_world(_prev: HelloEntry) {
+    r_println!("Hello, World!")
+}
+
+// Fallbacks
+#[renderer]
+fn fallback_dispatcher_not_found(prev: DispatcherNotFound) {
+    r_println!("Dispatcher not found for command `{}`", prev.join(", "))
+}
+
+#[renderer]
+fn fallback_renderer_not_found(prev: RendererNotFound) {
+    r_println!("Renderer not found `{}`", *prev)
+}
+
+// Collect renderers and chains to generate ThisProgram
+gen_program!();
+```
+
+Output:
+
+```
+> mycmd hello
+Hello, World!
+> mycmd hallo
+Dispatcher not found for command `hallo`
+```
