 This repository contains the InnerSource Patterns collected by the [InnerSource Commons][isc-website]. These patterns are InnerSource best practices codified in a specific format to make it easy to understand, evaluate, and reuse them.
 
+If you are here for the first time, you may start by reading our most mature patterns, published at [innersourcecommons.gitbook.io/innersource-patterns](https://innersourcecommons.gitbook.io/innersource-patterns/).
