Noob question but here it goes. The place I work at has a website written in CodeIgniter, a PHP framework. The creator of the codebase was contracted and when he gave me a demo, the code was just sitting in /home/www-user/public_html of the VPS and to show the code and make changes to it, he used FileZilla's "View/Edit" option.
I am not good at web dev but this seems like terrible practice. I have made a git repository out of the code but I am not sure how to proceed with deploying the changes I make in the repo to the production.
This is super noob so I am embarrassed to ask this but what software, resources, etc. can I look into to learn how to deploy? I have never done this shit so I am stumbling in the dark here.
