In order to maintain consistency across all lessons and contributions, this guide defines a set of styles to be used throughout.

• Use elixir code blocks
• Keep examples simple when possible
• Module definitions should not include the IEx prompt
• References to functions should include the arity. For example, Enum.map/2 instead of Enum.map.

• Use elixir code blocks
• Do not include line number in iex prompt (i.e. iex> vs iex(1)>). This can be configured with IEx.configure(default_prompt: "%prefix>"):

iex(2)> IEx.configure(default_prompt: "%prefix>")
:ok
iex> case :ok do
...> :ok -> "Hi"
...> _ -> "Other"
...> end
"Hi"

• Use erlang code blocks
• Keep examples simple and to the point
• Use number> for shell prompt indication. For Example:

1> is_list('Example').
false
2> is_list("Example").
true

• Use shell code blocks
• Terminal prompt character should be $:

$ mix deps.get
$ mix docs

• Lists should not be numbered
• Use - when separating a word and its definition:

+ `@moduledoc` - For module level documentation.

Please put one whitespace line before and after all markdown headers.
