 ## Usage Tips
 
-To avoid rate limiting and optimize your experience:
-
 - Consider using free models (e.g., Gemini, Mistral, Openrouter) as the `weak-model`
 - Use architect mode sparingly
 - Disable `yes-always` in your aider configuration

+- Be mindful that Claude 3.7 thinking mode consumes more tokens
+- Enable the `--manual` flag to review and approve each request before processing
+- If you have a GitHub Business account with Copilot, use the `--business` flag
+
+### Manual Request Approval
+
+When using the `--manual` flag, the server will prompt you to approve each incoming request:
+
+```
+? Accept incoming request? › (y/N)
+```
+
+This helps you control usage and monitor requests in real-time.
