+### Component Shorthand
+
+If the first argument to `m()` is a component, it acts as an alias of `m.component()`
+
+```javascript
+var MyComponent = {
+	controller: function() {
+		return {greeting: "hello"}
+	},
+	view: function(ctrl, args) {
+		return m("h1", ctrl.greeting + " " + args.data)
+	}
+}
+
+m.render(document.body, [
+	//the two lines below are equivalent
+	m(component, {data: "world"}),
+	m.component(component, {data: "world"})
+])
+```
+
+See [components](mithril.component.md) for more information.
