A minimalist writing zone, where you can block out all distractions and get to what\'s important. The writing!  \
</p>\
<p> \
	To get started, all you need to do is delete this text (seriously, just highlight it and hit delete), and fill the page with your own fantastic words. You can even change the title!  \
</p> \
<p> \
	You can use <b>bold</b>, <i>italics</i>, <b><i>both</i></b> and <a href="http://zenpen.io"> urls </a> just by highlighting the text and selecting them from the tiny options box that appears above it.\
</p>\
<blockquote>\
	Quotes are easy to add too!\

	If you\'re using ZenPen, and want to contribute a few dollars, there\'s a small donate button on the bottom left.\
