-This section provides information on how to choose and configure your primary domain.
+## Considerations 
+Before you configure a primay domain consider the following: 
+* WordPress Multisites should not use this configuration as it will conflict with subsite routing 
+* Sites already managing redirects for secondary domains via PHP should not use this configuration 
+  * For example, if you are redirecting `one-example.com` to `example.com/one` via [PHP redirects](/guides/redirect/advanced)
