-## Tips to not hit the rate limit
+## Usage Tips
 
-- Use a free model from free provider like Gemini/Mistral/Openrouter for the weak model
-- Rarely use architect mode
-- Do not enable automatic yes in aider config
-- Claude 3.7 thinking mode uses more tokens. Use it sparingly
+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 consume more tokens
+
+## Roadmap
+
+- [ ] Manual authentication flow
+- [ ] Manual request approval system
+- [ ] Rate limiting implementation
+- [ ] Token usage tracking and monitoring
+- [ ] Enhanced error handling and recovery
