When you sign up for Google Analytics, you're given an ID (something like
G-1234567ABC). You can find it by going to your Google Analytics dashboard, and looking next to the site name.
Copy that code, go to your Project Settings on ReadMe (Configuration > Integrations), and enter it in as your Google Analytics ID.
This will start streaming basic analytics (i.e. page views) to your Google Analytics account.
