[Video] Do we need to introduce Elixir from the bare basics?

In the learn-elixir README we give installation instructions and the links to some (awesome) videos and a link to elixirschool.com to get the user acquainted with what Elixir is.

Do we need to have an introduction to what Elixir is in our own videos, or should we just suggest that the user watches the videos/reads the material linked in the README? I suppose it depends on whether we want these videos to be able to completely stand on their own, or to be an accompaniment to the README of the learn-elixir repo.

I can see arguments for both so am keen for input!
