 ## Using Omnibus GitLab
 
 If you installed GitLab using the Omnibus packages (highly recommended):
 
-1. [Install GitLab Enterprise Edition](https://about.gitlab.com/install/) on the server that will serve as the **secondary** node. Do not create an account or log in to the new **secondary** node.
-1. [Upload the GitLab License](../../../user/admin_area/license.md) on the **primary** node to unlock Geo. The license must be for [GitLab Premium](https://about.gitlab.com/pricing/) or higher.
+1. [Install GitLab Enterprise Edition](https://about.gitlab.com/install/) on the node(s) that will serve as the **secondary** site. Do not create an account or log in to the new **secondary** site.
+1. [Upload the GitLab License](../../../user/admin_area/license.md) on the **primary** site to unlock Geo. The license must be for [GitLab Premium](https://about.gitlab.com/pricing/) or higher.
 1. [Set up the database replication](database.md) (`primary (read-write) <-> secondary (read-only)` topology).
-1. [Configure fast lookup of authorized SSH keys in the database](../../operations/fast_ssh_key_lookup.md). This step is required and needs to be done on **both** the **primary** and **secondary** nodes.
-1. [Configure GitLab](../replication/configuration.md) to set the **primary** and **secondary** nodes.
-1. Optional: [Configure a secondary LDAP server](../../auth/ldap/index.md) for the **secondary** node. See [notes on LDAP](../index.md#ldap).
