Summary

This PR improves the README installation documentation by adding virtual environment setup instructions and restructuring the "Create your first app" section into clear numbered steps. The changes address a common user issue where the reflex CLI command is not found when installed without a virtual environment due to PATH configuration problems.

Key improvements:

• Added prominent warning recommending virtual environment usage before installation
• Restructured quickstart into 5 clear numbered steps (create directory, setup venv, install, initialize, run)
• Added platform-specific virtual environment commands for Windows and macOS/Linux
• Included troubleshooting section with fallback python3 -m reflex command syntax

The documentation now aligns with the Reflex website installation guide and provides a better onboarding experience for new users.

Confidence Score: 5/5

• This PR is safe to merge with minimal risk - it only modifies documentation without touching any code
• Documentation-only change with clear improvements to user onboarding experience. The virtual environment setup instructions follow Python best practices and match industry standards. The only minor consideration is that localized README files were not updated, but this doesn't impact functionality.
• No files require special attention
