Improve setup documentation

[TicaGit]

Description:

While setting up the project, I ran into a few small issues that might affect other as well. I’ve updated the README.md with additional setup instructions. Additionally, I made minor modifications to config.py because it wasn't correctly sourcing the environment variables.
