The Erlang language is described in the 
<a href="reference_manual/users_guide.html">Erlang Reference Manual</a>. 
An Erlang tutorial can be found in 
<a href="getting_started/users_guide.html">
Getting Started With Erlang</a>.
<p>
In addition to the documentation here Erlang is described in several books like:
</p>
<ul>
<li>
<a href="https://www.oreilly.com/library/view/introducing-erlang-2nd/9781491973363">"Introducing Erlang"</a> from O'Reilly.
</li>
<li>
<a href="https://www.nostarch.com/erlang">"Learn You Some Erlang for Great Good!"</a> from No Starch Press.
</li>
<li>
<a href="https://www.oreilly.com/library/view/erlang-programming/9780596803940">"Erlang Programming"</a> from O'Reilly.
</li>
<li>
<a href="https://www.pragprog.com/titles/jaerlang2/programming-erlang-2nd-edition/">"Programming Erlang"</a> from Pragmatic.
</li>
<li>
<a href="https://www.manning.com/logan">"Erlang and OTP in Action"</a> from Manning.
</li>
<li>
<a href="https://shop.oreilly.com/product/0636920024149.do">"Designing for Scalability with Erlang/OTP"</a> from O'Reilly.
</li>
</ul>
<p>
These books are highly recommended as a start for learning Erlang. 
</p>
<p>
  More information about learning resources, editors and other tools can be found on our
  <a href="https://erlang.org/community">official Erlang web site</a>. 
</p>
</li>
<li>Erlang/OTP is divided into a number of OTP <a
href="applications.html">applications</a>. An application normally contains
Erlang <a href="man_index.html">modules</a>. Some OTP applications,
such as the C interface <em>erl_interface</em>, are written in other languages and have no Erlang
modules.
<p></p>
</li>

<p>
<li>When developing with Erlang/OTP you usually test your programs
from the interactive shell (see <a href="getting_started/users_guide.html">
Getting Started With Erlang</a>) where you can call individual
functions. There is also a number of tools available, such as the graphical <a
href="#debugger#/index.html" >Debugger</a> and the <a href="#observer#/index.html" >Observer tool</a> for inspection of system information, ets and mnesia tables  etc.
</p>

<li>For questions and discussions about Erlang we recommend <a href="https://erlangforums.com">
ErlangForums</a>.
<p></p>
</li>

<li>There is also the <a href="https://www.erlang.org/faq/faq.html" >Frequently
Asked Questions</a> which can be of interest.
<p></p>
</li>

<li>Additional information and links of interest for Erlang programmers can be found on the Erlang Open Source site 
<a href="https://www.erlang.org/">https://www.erlang.org</a>.
