It's tricky to put highlighted HTML (or JSP) in Wiki, but not impossible:
<body jwcid="@Body">
<form jwcid="welcomeForm@Form">
<span jwcid="welcome@Block">
<span jwcid="homeHeader">Pageheader</span>
<p>
<b>Use the application from the convenience of your
desktop</b><br/>
order ice cream, bread and other goods, monitor progress
all without distractions
</p>
….
<img src="images/Application.jpg" alt="application"/>
</span>
<input jwcid="@Hidden" id="hiddenId"
value="ognl:setBlockValue()" encode="false"/>
<span jwcid="@RenderBlock"
block="ognl:getComponent('welcome')"/>
</form>
</body>
