Getting started with django

Once you have installed django on your machine, you are ready to get started. In django

• Every web app you want to create is called a project;
• A project is a sum of applications.

An application is a set of code files relying on the MVT pattern. As example let's say we want to build a website, the website is our project and, the forum, news, contact engine are applications. This structure makes it easier to move an application between projects since every application is independent.

$django-admin startproject project
$cd project
