Hey! I noticed that deploying a simple flask app on a VPS is quite complicated and should run lots of commands each time I commit something on the project's repo, so I decided to create bunch of bash files to automate this.

source execute.sh my_domain worker_count

all those complex jobs now will done in a single command, it will setup nginx and gunicorn and installing all dependencies and requirements in fastest time.
