[Feature Request] Simplify Multi-Environment Setup Instructions

[shadowmoonezios]

Summary

The current README provides an overview of the Sealos platform, but it lacks detailed instructions on how to set up and manage multiple development environments. As developers might often need to work with different configurations or versions, having a clear guide would enhance usability and help users fully leverage Sealos' capabilities.

Suggested Enhancements

1. Add a Section: Include a dedicated section in the README that walks users through setting up multiple environments—highlighting best practices, commands, and configurations.
2. Example Configurations: Share example configuration files for common multi-environment setups.
3. Link to Further Documentation: If there is existing documentation or tools related to this feature, provide links to them within this section.

Benefits

• Improves onboarding experience for new users.
• Reduces potential confusion for developers looking to scale their projects across different environments.
• Encourages more efficient use of the platform's capabilities.

This improvement aligns with the project’s goal of creating a seamless development lifecycle and making it accessible for various user scenarios.
