References

• When source .env is executed in terminal, the commands in the .env file will be executed. This will save you time, not needing to activate the isolated environment and export env variables.
• The heroku.sh file (called by Procfile) allows Heroku to run 2 processes in the same dyno. (Not recommended for actual production applications)
