+This lesson shows how to use
+[Software Carpentry]({{ site.swc_site }})'s lesson template.
+Each lesson is made up of *episodes* that are 10-30 minutes long
+(including time for both teaching and exercises).
+The episodes of this lesson explain the tools we use to create lessons
+and the formatting rules those lessons must follow.
+
+Every lesson's home page is contained in `index.md`,
+and opens with a few pages
+After that come
+a block stating prerequisites
+and a line including `syllabus.html`
+(which generates a summary of the lesson's episodes).
+
+> ## Prerequisites
+>
+> Use the `.prereq` style to specify prerequisites.
