 ## Putting it together: Fetching Misdemeanours
 
 👉 Use `fetch` in your application to get misdemeanour data from the server, with the constraint that you ONLY want to fetch new data when you hit `F5` or otherwise fully refresh the page.
 
-👉 Make this state accessible via `useContext` so you can consume it in sub-components you will write next
+💡 Hint: `useEffect` can help here. If you don't pass any dependencies into the dependency array, it will only fire once!
 
 ❗ The `fetch` function is asynchronous so be sure to `await` the results.
 
-❗ The response from a `fetch` has an async convenience method called `.json`. You can `await` the result of this to get the JSON body of the response.

 ❗ Think about where your `fetch` should live. Can you abstract the `fetch` code outside of your components? Which component should "own" this data?
