+# Adding Google Analytics
+
+## Setup
+
+Including Google analytics to your flask-base app is incredibly easy. Simply add an environment variable named `GOOGLE_ANALYTICS_ID` to a local file called `.env`.
+
+A Google analytics ID can be obtained by signing up [here](https://analytics.google.com/analytics/web). The ID should be of the form `UA-XXXXXX-X`.
+
+For more information about using Google analytics, check out their [help center](https://support.google.com/analytics#topic=3544906).
