+Let's use a Reddit post as an example:
 
 ![Reddit Post](../images/reddit_post.png)
 
-We can build this post as a component, consisting of multiple subcomponents. It has several inputs:
-
-- The score
-- The number of comments
-- How long ago it was posted
-- The url short address
-- The title
-- The username of the original poster

-If we wanted to sketch out these requirements in Rust, we would start with a struct:

-    url: String,

 ## Props
-All properties that your components take must implement the `Props` trait. We can derive this trait on our own structs to define a Component's props.
+The input of your Component must be passed in a single struct, which must implement the `Props` trait. We can derive this trait automatically with `#[derive(Props)]`.

 Owned Props are very simple – they don't borrow anything. Example:

-struct MyProps {

+#[derive(PartialEq, Props)]

+            div { "-" }

+    ))
 }

 ### Borrowed Props
 
-Owning a string works well as long as you only need it in one place. But what if we need to pass a String from a `Post` Component to a `TitleCard` subcomponent? A naive solution might be to [`.clone()`](https://doc.rust-lang.org/std/clone/trait.Clone.html) the String, creating a copy of it – but this would be inefficient, especially for larger Strings.
+Owning props works well if your props are easy to copy around - like a single number. But what if we need to pass a larger data type, like a String from an `App` Component to a `TitleCard` subcomponent? A naive solution might be to [`.clone()`](https://doc.rust-lang.org/std/clone/trait.Clone.html) the String, creating a copy of it for the subcomponent – but this would be inefficient, especially for larger Strings.
 
 Rust allows for something more efficient – borrowing the String as a `&str`. Instead of creating a copy, this will give us a reference to the original String – this is what Borrowed Props are for!
