Welcome to Erlang/OTP, a complete
for concurrent programming.
Some hints that may get you started faster
- The Erlang programming language is described in the book
Concurrent Programming in Erlang, ISBN 0-13-285792-8, 2nd
edition. The first part of the book is available as a PDF
document. The language has evolved since the book was written and
there is a separate description of the language
extensions since Erlang 4.4.
- Erlang/OTP is divided into a number of OTP applications. An application normally contains
Erlang modules. Some OTP applications,
like the C interface, are written in other languages and have no Erlang
Note that functions that are not imported or prefixed with a module
name belong to the built in module erlang
- On a Unix system you can view the manual pages from the command
% erl -man <module name>

- When developing with Erlang/OTP you usually test your programs
from the interactive shell
where you can call individual functions. You can also start the
process monitor and
table viewer from the shell.
Also note that there are some shell features like history list (control-p
and control-n), in line editing (emacs key bindings) and module and
function name completion (tab) if the module is loaded.

- A fast way to learn the Erlang language and OTP is attending one
of the courses offered by
Ericsson and others.
There is also a certification program.
