+Let's start slow by creating the HTML and CSS we need to make the app look like the design: do this is `App.js` and `App.css`
 
 Don't worry about fetching data yet, you can use **invented, "hardcoded"** values for now - just focus on getting content up on the page and imitating the design provided. However, do not leave out the values!  Put numbers in so that you can confirm how the layout will work with numbers present.  Using the numbers that occur in the screenshot is a good idea.
 
 A few things to think of:
 
 - The font you need is called `Raleway` and is already loaded up into the project - but remember you'll need to declare it in your CSS.
 - You'll need to copy the colours, spacing, layout and size of elements in the design. This is a core skill as a front-end developer! :)
-- Use placeholder images (such as [these kittens](https://placekitten.com/) ), initially.
-- Extra points if you can think of a nice way to display the app on mobile ;)
+- The weather icons you need are in the `img/weather-icons` folder, but you can use a placeholder image like [this one](https://cdn2.iconfinder.com/data/icons/weather-flat-14/64/weather02-512.png) for now if that's easier. See the next section below for help with images.
+- Extra points if you use media queries to make the app responsive ;)
 
 #### A note on using images in React
 
-Once you have your design working with placeholder images, you can try using the weather icons we've provided.
-
 There is a special way to show images from a React app created with create-react-app.  You can [read about how to add and use images in a create-react-app project in the official docs](https://facebook.github.io/create-react-app/docs/adding-images-fonts-and-files), but in short, you'll need to do these two things:
