The big picture (read this before starting)

Three things are involved, and they talk to each other like this:

 Your laptop          GitHub                     Your Hostinger VPS
 (where you and  ───▶  (a website that stores  ───▶ (runs 24/7 and is
  Claude Code           a copy of your code           reachable at your
  write code)           and its full history)         domain name)

• Your laptop is where you and Claude Code actually write and test the website.
• GitHub is a free website that stores a backup copy of your code and every change ever made to it (this is called "version control"). It's also the handoff point between your laptop and the VPS.
• The VPS (Virtual Private Server) is a computer you rent from Hostinger that's always switched on and connected to the internet, identified by an IP address (a string of numbers like 203.0.113.5 that works like a street address for computers). You manage it through hPanel, Hostinger's web-based control panel.

The code always flows in one direction: laptop → GitHub → VPS. You never edit code directly on the VPS itself.
