📋 Deployment Steps

1. Pre-deployment

   • Complete this checklist
   • Create git tag: git tag v1.0.0
   • Push tag: git push origin v1.0.0

2. Deployment

   • Deploy to staging first (if available)
   • Test on staging
   • Deploy to production
   • Monitor for 15-30 minutes

3. Post-deployment

   • Verify application working
   • Check error logs
   • Monitor performance
   • Notify stakeholders

4. If issues occur

   • Check error tracking service
   • Review server logs
   • Rollback if necessary
   • Document issue for post-mortem

📝 Deployment Log

Keep a record of deployments:

Date	Version	Deployed By	Status	Notes
YYYY-MM-DD	v1.0.0	Name	✅/❌	Initial production release

🎯 Success Criteria

Deployment is successful when:

• ✅ Application loads without errors
• ✅ All critical features working
• ✅ No increase in error rate
• ✅ Performance within acceptable range
• ✅ No security vulnerabilities detected
• ✅ Monitoring and alerts active

📞 Support

If you encounter issues:

1. Check DEPLOYMENT.md troubleshooting section
2. Review error logs in monitoring service
3. Check browser console for client-side errors
4. Verify API connectivity
5. Contact backend team if API issues
6. Rollback if critical issues persist

Remember: It's better to delay deployment than to deploy with known issues. Take your time and verify each step.

Good luck with your deployment! 🚀
