How much clarity is needed for beginners?

Should we assume Elixir is unlikely to be someone's _first_ attempt beyond a simple understanding of the basics?

I'm wondering how much we need to add small notes to clarify things like for example what an enumerable is [here](https://github.com/dwyl/learn-elixir/blame/master/README.md#L275):
> Lists are enumerable, the [Enum](https://hexdocs.pm/elixir/Enum.html) module provides lots of useful functions.

Or:
+ What an `anonymous function` is
+ The Elixir `/` syntax for named functions
+ What a `macro` is
