## Version : 0.0.7-2
## Developer : Yannyann (https://github.com/a2d8a4v)
## This file is also referenced from cerbot-auto and easyengine 4 install shell script as example
## Thanks for @wartw98 at Github help me fix the openssh-serve attended installation problem.
## For the installition will take some time, i think it is better to run some tools like "screen" make the script run 
## even if the terminal disconnect with the vps
## 
## Let's start install!! Enjoy it!
