   - User logging in into GitLab
 
-The data is stored in Redis and it depends on it for being recorded and displayed
-over time. This means that we will lose the data if Redis gets flushed, or a custom
-TTL is reached.
-
 By default, it shows the activity for all users in the last 6 months, but this can be
 amended by using the `from` parameter.
 
-This function takes pagination parameters `page` and `per_page` to restrict the list of users.
