+      Elixir is a functional, meta-programming aware language built on
+      top of the Erlang VM. It is a dynamic language with flexible
+      syntax and macro support that leverages Erlang's abilities to
+      build concurrent, distributed and fault-tolerant applications
+      with hot code upgrades.
