$> cd /path/to/your-project-folder
$> python -m SimpleHTTPServer 8080

1. Open a browser and visit localhost:8080
2. Download and install ngrok to make your local server accessible remotely. Note that I needed to add http infront of ngrok 8080 on my system unlike the original directions given for this assignment

$> cd /path/to/your-project-folder
$> http ngrok 8080

1. Copy the public URL ngrok gives you and try running it through PageSpeed Insights!
