 So, let's create a **virtual environment** (also called a *virtualenv*). Virtualenv will isolate your Python/Django setup on a per-project basis. This means that any changes you make to one website won't affect any others you're also developing. Neat, right?

 When you send a letter, it needs to have certain features to be delivered correctly: an address, a stamp, etc. You also use a language that the receiver understands, right? The same applies to the *data packets* you send to see a website. We use a protocol called HTTP (Hypertext Transfer Protocol).
