 ## Using with `create-react-app`, Gatsby, and other development servers
 
+### Why you need to proxy (for beginners)
+
 `react-scripts` (the underlying library for `create-react-app`) and other popular development servers often set up catchall serving for you; in other words, if you try to request a route that doesn't exist, the dev server will try to serve you `/index.html`. This is problematic when you are trying to hit a local API endpoint like `netlify-lambda` sets up for you - your browser will attempt to parse the `index.html` file as JSON. This is why you may see this error:
 
 `Uncaught (in promise) SyntaxError: Unexpected token < in JSON at position 0`
