This document discusses Ariane, a breadcrumbs gem for Rails applications. It provides flexibility and facilitates both usage and participation. Ariane allows adding breadcrumbs in controllers and views, rendering them with default or custom renderers, and configuring options like the divider and renderer parameters. Future goals include dynamic breadcrumbs and syntactic sugar. Resources include the Github repository and the author's Twitter account.
