Explain graphically different steps of a typical use of Tails through photos or screencast

From a UX session :

For a first-time user it’s quite difficult to get was Tails realy is : a key, a software, something you install on your computer ? It quite difficult to get how it works, from the user point of view, especialy when you don’t even know it might be possible to have an Operating System running on a USB key.

We could do graphics, a screencast or a gif that could show the differents steps of a usal use of Tails.

We could have this steps (maybe less, this could be split in differents things too.) :

- Usual OS screen

- Switch off

- Show the Key / DVD / SD Card etc.

- Plug in the key

- Boot

- Bios

- Select tails

- More options

- Tails

- Pull out the key
- Reboot and windows

We could add this material to the homepage.
