To use any of Google's powerful APIs we need to get setup on the Google Developer Console. Follow these steps:

1. Go to tha Google Developer Console and click on "create an empty project"

2. Once in your project dashboard, go to the top left and open the left sidebar. Navigate to "API Manager"

3. Click "OAuth consent screen" tab -> Enter your product name (can be any gibberish)and then save.

4. Click "Credentials" tab -> click "Add credentials" -> click "API Key" -> choose "Server key".

5. Click "create" -> Copy and save the API Key that it gives you!

We will use this key whenever trying to make an API request to Google's many awesome API services.
