+Argument components are components passed down as arguments.
 
-It could be written by you!, if you want <3
+Here is an example of a `Greeter` component being passed down `Me` component as `@person` argument:
+
+```gjs
+const Me = <template>
+  NullVoxPopuli
+</template>;
+
+const Greeter = <template>
+  Hello <@person />!
+</template>;
+
+<template>
+  <Greeter @person={{Me}} />
+</template>
+```
+
+This pattern can be also used in cases where a _component A_ `yields` _component B_ and this one then needs to be used in _component C_:
+
+```gjs
+import { hash } from '@ember/helper';
+
+const Button = <template>
+  <button type="button">Close</button>
+</template>;
+
+const Sidebar = <template>
+  <side>
+    {{yield (hash closeButton=Button)}}
+  </side>
+</template>;
+
+const Menu = <template>
+  <nav>
+    <ul>
+      <li>Home</li>
+      <li>About</li>
+    </ul>
+  </nav>
+
+  <@closeMenu />
+</template>;
+
+<template>
+  <Sidebar as |side|>
+    <Menu @closeMenu={{side.closeButton}} />
+  </Sidebar>
+</template>;
+```
