 A component is a Rust function, named in UpperCammelCase, that takes a `Scope` parameter and returns an `Element` describing the UI it wants to render. In fact, our `App` function is a component!
 
 ```rust
-{{#include ../../examples/hello_world_desktop.rs:component}}

 A Component is responsible for some rendering task – typically, rendering an isolated part of the user interface. For example, you could have an `About` component that renders a short description of Dioxus Labs:
 
 ```rust
-{{#include ../../examples/components.rs:About}}
+{{#include ../../../examples/components.rs:About}}
 ```
 
 Then, you can render your component in another component, similarly to how elements are rendered:
 
 ```rust
-{{#include ../../examples/components.rs:App}}
+{{#include ../../../examples/components.rs:App}}
 ```
