 # Reference architecture: up to 3,000 users **(PREMIUM SELF)**
 
-This page describes GitLab reference architecture for up to 3,000 users.
-It is designed to help your organization achieve a
-highly-available GitLab deployment. If you do not have the expertise or need to
-maintain a highly-available environment, you can have a simpler and less
-costly-to-operate environment by using the
-[2,000-user reference architecture](2k_users.md).
-If you have fewer than 3,000 users and still want a highly-available GitLab deployment,
-you should still use this reference architecture but scale down the node sizes.
+This GitLab reference architecture can help you deploy GitLab to up to 3,000
+users, and then maintain uptime and access for those users. You can also use
+this architecture to provide improved GitLab uptime and availability for fewer
+than 3,000 users. For fewer users, reduce the stated node sizes as needed.
+
+If maintining a high level of uptime for your GitLab environment isn't a
+requirement, or if you don't have the expertise to maintain this sort of
+environment, we recommend using the [2,000-user reference architecture](2k_users.md)
+for your GitLab installation.
 
 For a full list of reference architectures, see
 [Available reference architectures](index.md#available-reference-architectures).
