 In some cases, you may wish to create a component that acts as a container for some other content, without the component needing to know what that content is. To achieve this, create a prop of type `Element`:
 
 ```rust
-{{#include ../../examples/component_element_props.rs:Clickable}}
+{{#include ../../../examples/component_element_props.rs:Clickable}}
 ```
 
 Then, when rendering the component, you can pass in the output of `cx.render(rsx!(...))`:
 
 ```rust
-{{#include ../../examples/component_element_props.rs:Clickable_usage}}
+{{#include ../../../examples/component_element_props.rs:Clickable_usage}}
 ```
 
 > Note: Since `Element<'a>` is a borrowed prop, there will be no memoization.

 Rather than passing the RSX through a regular prop, you may wish to accept children similarly to how elements can have children. The "magic" `children` prop lets you achieve this:
 
 ```rust
-{{#include ../../examples/component_children.rs:Clickable}}
+{{#include ../../../examples/component_children.rs:Clickable}}
 ```
 
 This makes using the component much simpler: simply put the RSX inside the `{}` brackets – and there is no need for a `render` call or another macro!
