Add README.md with required envs to the spring-app #218
Description
While developing on multiple devices, I ran into an issue where I need to add some environments to my spring run configuration.
It would be nice to have a document telling me what environments I need to add. Right now if I don't add anything then the app won't start on it's own.
Another option is to implement files for the running environment as we are doing it right now on the frontend side.
For example; for dev env we do have a file named .env.development and for the production .env.production which is a very simple way to store your envs that can change depending on which way you are using the app.
