Extended information on deployment

I have updated the file. Any errors,shout out. I would be obliged to correct it.
And also anything more needs to be added?
I thought of also adding 'Common errors while installing'
Ideas?
Apache is a daemon, a daemon should start automatically each time you powerup the machine, even in arch all you have to do is systemctl enable httpd
maybe you should consider enabling apache in your systemd configuration or by enabling an init.d script
