I've had to install and configure these things a few times, and I always forget how to do it, so here it is for posterity:

• Update brew and install pandoc:

  brew update
  brew install pandoc
  

• Install mactex from https://www.tug.org/mactex/

Learning Erlang / Elixir Basics

Primitives

Erlang only has a few primitives that you need to worry about. Here they are below with corresponding Elixir examples.

1. integer: Erlang: 123, Elixir: 123
2. float: Erlang: 123.5, Elixir: 123.5
3. atom: Erlang: hello, Elixir: :hello
4. binary: Erlang: <<"hello">> or <<10,20>>, Elixir: "hello" or <<10,20>>
