<h2 id="learning">Learning Go</h2>

<p>
If you're new to Go, we recommend you work through the 
<a href="go_tutorial.html">tutorial</a>. The 
<a href="go_spec.html">language specification</a> has all the details should
you want to explore.
</p>
<p>
Once you've learned a little about the language, 
<a href="effective_go.html">Effective Go</a> will help you learn the style and
idioms of programming in Go.
</p>

<h3 id="go_tour"><a href="http://go-tour.appspot.com/">A Tour of Go</a></h3>
<p>
An interactive introduction to Go in three sections.
The first section covers basic syntax and data structures; the second discusses
methods and interfaces; and the third introduces Go's concurrency primitives.
Each section concludes with a few exercises so you can practice what you've
learned. You can <a href="http://go-tour.appspot.com/">take the tour online</a> or
<a href="http://code.google.com/p/go-tour/">install it locally</a>.

</p>
<p><i>
Go’s approach to concurrency differs from that of many languages, even those
(such as Erlang) that make concurrency central, yet it has deep roots. The path
from Hoare’s 1978 paper to Go provides insight into how and why Go works as it
does.
