>Let's try this program using the online Faust IDE:</p>
<!-- faust-run -->
<div class="faust-run"><img src="exfaust0/exfaust0.svg" class="mx-auto d-block">
<faust-editor><!--

process = _;

--></faust-editor>
<br>
</div>
<!-- /faust-run -->

<p>Several lessons can be learned from this very simple example:</p>
<ul>
<li>a Faust program has at least one definition, that of the keyword <code>process</code> which indicates the entry point of the program. </li>
<li>a definition always ends with a <code>;</code>.
