 ## Contents
-This repo contains several tutorial files, with varying levels of difficulty.  Recommended prerequisites will be listed near the top of that tutorial. However, try as I might to make them so, there's no guarantee that each tutorial is entirely self-contained, but the idea is that you should be able to start anywhere.
+This is a collection of _get started_ pages and introductory tutorials for computational methods routinely used within the group, followed by details on access to high-performance computing access within Monash, and links to bioinformatics beginners tutorials.  Recommended prerequisites are listed at the top of that page. However, try as I might to make them so, there's no guarantee that each tutorial is entirely self-contained, but the idea is that you should be able to start anywhere.
