+About Splunk Observability Cloud realms
+====================================================================================
+
+A realm is a self-contained deployment that hosts your organization. 
+
+Wherever you see ``<REALM>``, replace it with the name of your organization's realm. For example, if your realm is ``eu0``, change the endpoint ``https://api.<REALM>.signalfx.com`` to ``https://api.eu0.signalfx.com``.
+
+.. caution:: If you don't include your realm and use ``https://api.signalfx.com``, Splunk Observability Cloud interprets the endpoint as pointing to the ``us0`` realm.
