 ### Setup
 
-Configure the environment for your Agent Observability deployment. Do not mix
-O11y Cloud and standalone deployment variables; the SDK detects the deployment
-from the variables that are present and rejects ambiguous configurations.
+Environment variables differ based on your Agent Observability deployment:
+1. On-premises, standalone, and custom deployments
+2. Splunk Observability (O11y) Cloud deployments
