+		<h3 id="builtin_setlocal">ste:set</h3>
+			<p>ste:setlocal is used like <a href="#builtin_set">ste:set</a>, but only a local variable will be set (ste:set would overwrite a variable, if it was declared in a parent scope).
+		
 		<h3 id="builtin_get">ste:get</h3>
 			<p>ste:get will return the content of a variable. The parameter <code>var</code> takes the name of the variable to get. Useful, if you want to get a variable which name is stored in a variable.</p>
