Code Review

This pull request introduces essential documentation for setting up the development and deployment environment, including a setup guide and an environment variable template. The changes are well-structured and significantly improve the onboarding experience for new developers. My review includes a few suggestions to enhance clarity, consistency, and security within the new documentation. Specifically, I've recommended aligning the SECRET_KEY placeholder between files, adding configuration for the logs directory, and making the setup and security instructions more explicit and actionable.
