+description: A component can maintain its own state and render information depending on it
+---
+
+# Internal state
+
+The component can manage it's own state using a struct that implement the trait `Component`. The HTML rendering is based on this state.
+When the state change the component might be re-rendered.
+
+```rust
+use yew::prelude::*;
+
+pub struct InternalStateComponent {
+    name:String,
+}
+
+impl Component for InternalStateComponent {
+    type Message = ();
+    type Properties = ();
+
+    fn create(_props: Self::Properties, _link: ComponentLink<Self>) -> Self {
+        Self {
+            name: "Clark".into(),
+        }
+    }
+
+    fn update(&mut self, _msg: Self::Message) -> ShouldRender {
+        false
+    }
+
+    fn change(&mut self, _props: Self::Properties) -> ShouldRender {
+        false
+    }
+
+    fn view(&self) -> Html {
+        html! {
+            <>
+                <h1>{format!("Hello {}",self.name)}</h1>
+            </>
+        }
+    }
+}
+```
+
+## Defining state
+
+Here we add the `name` field to the struct
+
+```rust
+// ...
+pub struct InternalStateComponent {
+    name:String,
+}
+// ...
+```
+
+## State initialization
+
+The component lifecycle will initialize the state in the `create` method.
+
+```rust
+// ...
+    fn create(_props: Self::Properties, _link: ComponentLink<Self>) -> Self {
+        Self {
+            name: "Clark".into(),
+        }
+    }
+// ...
+```
+
+## Rendering using the state
+
+Using the `html!` macro we can render html using the state from the `view` method
+
+> please refer to the `html!` macro documentation page for more detail on how to render components as HTML
+
+```rust
+// ...
+    fn view(&self) -> Html {
+        html! {
+            <h1>{format!("Hello {}", self.name)}</h1>
+        }
+    }
+// ...
+# }
+```
