 [Browserbase](https://browserbase.com) provides remote browser infrastructure to make deployment of agentic browsing agents easy. Use it when running the agent-browser CLI in an environment where a local browser isn't feasible.
 
-To enable Browserbase, set these environment variables:
+To enable Browserbase, use the `-p` flag:
 
 ```bash
 export BROWSERBASE_API_KEY="your-api-key"
 export BROWSERBASE_PROJECT_ID="your-project-id"
+agent-browser -p browserbase open https://example.com
 ```
 
-When both variables are set, agent-browser automatically connects to a Browserbase session instead of launching a local browser. All commands work identically.
+Or use environment variables for CI/scripts:
+
+```bash
+export AGENT_BROWSER_PROVIDER=browserbase
+export BROWSERBASE_API_KEY="your-api-key"
+export BROWSERBASE_PROJECT_ID="your-project-id"
+agent-browser open https://example.com
+```
+
+When enabled, agent-browser connects to a Browserbase session instead of launching a local browser. All commands work identically.
 
 Get your API key and project ID from the [Browserbase Dashboard](https://browserbase.com/overview).
