How to build a website using Tor

Not a lot of people know about .onion websites, not many people actually use it.
ONION websites are used by people who want to stay anonymous.

First of All let's start with the requirements:

1. Tor Installed (For Windows) OR Downloaded and extracted (Linux)
2.  A Server like Apache. (Windows users are advised to use XAMPP and Linux users, you can simply install Apache2 on your machine.)
3. Text Editor.
