 ## Login in
 
-To login via ACO on gitlab.com, you must use the following link: [https://id.centos.org/gitlab](https://id.centos.org/gitlab)
+The first thing to understand is that gitlab will "link" an existing account
+with third party authentication system. In other words, you need to have a
+gitlab account and be logged in onto gitlab.com before you can associate your
+account with the CentOS Account System (ACO).
+
+So if you do not have a gitlab account, create one. Then visit the following
+link [https://id.centos.org/gitlab](https://id.centos.org/gitlab) to associate
+your account with CentOS' Account System.
+
+From there on, everytime you visit this link, your group membership defined in
+ACO, will be refreshed on gitlab.
