+    <p>Purl is an experimental tool that will help you create a course using GitHub pages. By "forking" Purl, you'll be building your own course and receive step-by-step instructions.</p>
+    <p>We made Purl to help folks learn some technical skills in the service of creating an open course. You'll use Jekyll, GitHub pages and Markdown, and at the same time tap the theories of social learning we use at P2PU. Put your stitch in the open web and get started. </p>
