+### Fitbit Credentials
+
+[Register a Fitbit application](https://dev.fitbit.com/apps/new). Note the client key and secret.
+
+Run `auth_fitbit.py` to get credentials for read access to a user's data,
+
+    $ python auth_fitbit.py [FITBIT CLIENT KEY] [FITBIT CLIENT SECRET] 
+
+This scripts open a browser window where you can log in to your Fitbit account and authorize the app to "access your profile and data". When you accept, the site will give you a string to copy and paste back into the script, which then writes the credentials to a local file named `fitbit.yaml`.

 ### Google Credentials
 
 [Create a project in Google Developers Console and enable the fitness API](https://console.developers.google.com/flows/enableapi?apiid=fitness). Note the client id and client secret.
 
 Run `auth_google.py` to get credentials for write access to a user's body data,
 
-    $ python auth_google.py [YOUR CLIENT ID] [YOUR CLIENT SECRET] https://www.googleapis.com/auth/fitness.body.write
+    $ python auth_google.py [GOOGLE CLIENT ID] [GOOGLE CLIENT SECRET] https://www.googleapis.com/auth/fitness.body.write
 
 This script opens a browser window where you can log in to your Google account and authorize the app to "View and store body sensor data in Google Fit". When you accept, the script writes the credentials to a local file named `google.json`.
