This article describes how repositories are structured in openSUSE, as well as listing some of the useful repositories not enabled by default at installation, and how to manage repositories using both the zypper tool and the YaST "Software Repositories" module. Although, originally written as a supplement to the openSUSE 13.2 review, it applies to newer versions of openSUSE's regular release as well as openSUSE's rolling release, Tumbleweed.
