Reason: This article is a stub. Can it be extended without duplicating the upstream docs? (Discuss in Talk:Erlang#)

Erlang is a programming language with the specific qualities of immutable data and distributed computing.

To activate the console, type in the command erl

Where you can enter commands like so:

   Eshell V10.1  (abort with ^G)
